INTEGRATED CIRCUITS DATA SHEET UAA3522HL Low power dual-band GSM transceiver with an image rejecting front-end Objective specification File under Integrated Circuits, IC17 2000 Feb 18 Philips Semiconductors Objective specification Low power dual-band GSM transceiver with an image rejecting front-end FEATURES The input Low Noise Amplifier (LNA) can be switched off via the bus to allow accurate calibration in the offset cancellation mode. • Dual-band application for Global System for Mobile communication (GSM) and Digital Cellular communication Systems (DCS) The transmitter comprises a high precision I/Q modulator and modulation loop architecture. The I/Q modulator converts the baseband modulation frequency to the transmit IF. The modulation loop architecture, which includes an on-chip offset mixer and phase detector, controls an external transmit RF VCO which converts the transmit modulated IF signal to RF. • Low noise and wide dynamic range single Intermediate Frequency (IF) transceiver • More than 30 dB on-chip image rejection in the receiver • More than 60 dB gain control range • I/Q demodulator with high performance integrated baseband channel filter A receive RF VCO provides the Local Oscillator (LO) signal to the image rejection mixers in the RF receiver. An IF VCO provides the LO signal to the I/Q demodulator and I/Q modulator in the receiver and transmitter sections respectively. • High precision I/Q modulator • Transmit modulation loop architecture including offset mixer and phase detector • Dual Phase-Locked Loop (PLL) with on-chip IF Voltage Controlled Oscillator (VCO) The frequencies of the RF VCO and the IF VCO are set by internal PLL circuits, which are programmable via the 3-wire serial bus. The RF and IF PLL comparison frequencies are 200 kHz and 1 MHz respectively, derived from a 13 MHz reference signal which has to be supplied externally. The quadrature RF LO signals required by the image rejection mixers are obtained using on-chip Resistor Capacitor (RC) networks. The quadrature IF LO signals required by the I/Q modulator and I/Q demodulator are obtained by dividing the frequency of the IF VCO signal. • Fully differential design minimizing cross-talk and spurii • 3-wire serial bus interface • Functional down to 2.7 V and up to 3.3 V • LQFP48 package. APPLICATIONS • GSM 900 MHz hand-held transceiver • GSM/DCS dual-band solution with the UAA2077CM (down to 3.2 V) or UAA2077TS/D (down to 2.7 V). The IC can be powered on in either receiver (RX), transmitter (TX) or synthesizer (SYN) operating mode depending on the logic level at pins RXON, TXON and SYNON, respectively. Alternatively, an operating mode can be selected by software using the 3-wire serial programming bus. In RX or TX mode, only those sections of the IC which are required are switched on. GENERAL DESCRIPTION The UAA3522HL integrates the receiver and most of the transmitter section of a GSM hand-held transceiver. It also integrates the receiver IF and the transmitter section of a DCS transceiver. The GSM or DCS band is selected by the 3-wire serial programming bus. When activating RX mode for DCS applications, the receiver RF section can be disabled by software so that only the receiver IF section is powered-on. The receiver comprises an RF and an IF section. The RF (GSM) front-end amplifies the aerial signal, converts the chosen channel frequency to an IF of 200 MHz, and also provides more than 30 dB of image suppression. Some selectivity is provided at this stage by an off-chip bandpass pre-filter. The IF section further amplifies the chosen channel, maintains the gain at the required level, demodulates the signal into I and Q components, and provides channel selectivity at a baseband stage using a high performance integrated low-pass filter. The IF gain can be varied over a range of more than 60 dB. The offset at the I and Q outputs can be cancelled out by software using the 3-wire serial programming bus. 2000 Feb 18 UAA3522HL The SYN mode is used to power-on the synthesizer prior to activating the RX or TX mode. In SYN mode, some internal LO buffers are also powered-on to minimize the ‘pulling’ effect of the VCO when either the receiver or the transmitter are switched on. 2 Philips Semiconductors Objective specification Low power dual-band GSM transceiver with an image rejecting front-end UAA3522HL QUICK REFERENCE DATA SYMBOL PARAMETER MIN.

A PLL of at least third-order is needed to meet noise requirements at 20 MHz offset from the carrier. RF receiver The receiver front-end converts the aerial RF signal, in the GSM band (925 to 960 MHz), to an IF signal of approximately 200 MHz. The first stage of the receiver is a symmetrical LNA that is matched to 50 Ω by an external balun. The LNA is followed by an image rejection mixer which suppresses the image by more than 30 dB. It comprises two mixers in parallel driven by 0° and 90° quadrature LO signals respectively. The IF signal from one mixer is shifted by 90° with respect to the IF signal from the other mixer, then both signals are added together to cancel out the image signal. The resultant IF signal is fed to the output via a high output impedance open-collector stage which drives an external Surface Acoustical Wave (SAW) filter which selects the required channel. RF and IF LO sections The active components required for the design of a low noise IF VCO are provided on-chip. Pins IFLOC and IFLOE connect the on-chip IF VCO components to an external resonator and feedback circuit. A divider and phase shifter divides the frequency of the IF VCO signal by 2 and splits it into two signals having phases of respectively 0° and 90° which are both fed to the I/Q modulator and to the I/Q demodulator. The IF VCO frequency is twice the IF to suppress the effects of self-mixing and parasitic VCO modulation. I/Q demodulator Pins TXIRFA and TXIRFAB connect an external receive RF VCO module to the on-chip RF LO section. This section includes a RC phase shifter which splits the RF VCO signal into two signals having phases of respectively 0° and 90° which are both fed to the RX image rejection mixer. The signal from the SAW filter enters the I/Q demodulator section. In addition to I/Q demodulation, this section performs Automatic Gain Control (AGC) over a range of 60 dB to maintain a constant output level irrespective of the antenna input level, and also applies additional channel selectivity at the baseband stage using an integrated high-order low-pass filter. Dual PLL An on-chip high performance dual PLL synthesizes the frequencies of the receive RF VCO and IF VCO signals. Very low close-in phase noise is achieved which provides a wide PLL bandwidth with a short settling time. The AGC amplifier output can be adjusted for a static offset of less than 50 mV. Its design prevents the offset from varying by more than ±5 mV. To allow a more accurate offset calibration, the RF LNA can be switched off to ensure that no IF signal is present at the AGC amplifier input during the offset measurement. A dual programmable divider chain reduces the frequency of the receive RF and IF LO signals to 200 kHz and 1 MHz respectively. A digital phase/frequency detector compares their phases to a reference signal derived from an external 13 MHz clock signal. Phase error information is fed back to both VCOs via the dual charge pump circuit which adjusts the phase of each VCO signal by either ‘sinking’ current into, or ‘sourcing’ current from, its loop filter capacitor, phase locking both RF and IF loops. The very low leakage current of the dual charge pump circuit ensures that any spurii are negligible. I/Q modulator Baseband I and Q signals are applied to the I/Q modulator which shifts the modulation spectrum up to the transmit IF. The I/Q modulator is designed for low harmonic distortion, low carrier leakage and high image rejection to keep the phase error as small as possible. Its IF output is loaded by an integrated low-pass filter and by an external LC tuned-circuit to prevent unwanted spurii from entering the phase detector in the transmit modulation loop. Operating modes BASIC OPERATING MODES Transmit modulation loop The circuit can be powered on in one of four operating modes in which different parts of the device are enabled or disabled. The four operating modes are called Idle, RX, TX and SYN, and are selected by the hardware control voltage level applied to pins RXON, TXON and SYNON. The analog transmit modulation loop comprises an on-chip offset mixer and simple phase detector in switching mode (triangular transfer function) forming an analog PLL with an off-chip loop filter and transmit RF VCO. 2000 Feb 18 7 Philips Semiconductors Objective specification Low power dual-band GSM transceiver with an image rejecting front-end Table 2 The synthesizer, receiver and transmitter cannot all be on at the same time. Table 1 shows which parts of the device are enabled (on) or disabled (off) in each mode. Table 1 UAA3522HL Bit LNA status BIT LNA STATUS POWER STATUS OF BIT LNA 0 off 1 on Operating modes POWER STATUS MODE SYNTHESIZER RECEIVER TRANSMITTER Idle off off off SYN on off off RX on on off TX on off on Table 3 The synthesizer includes the oscillators and LO buffers common to the receive and transmit sections. The receiver includes the RF section and the I/Q demodulator. When the receiver is on, the LNA can be switched off to allow DC offset compensation to be performed. The RF section can also be switched off for DCS applications. See Section “Receiver power status control”. BIT RF STATUS POWER STATUS OF RECEIVER RF SECTION IN RX MODE 1 on (GSM) 0 off (DCS) Programming SERIAL PROGRAMMING BUS A simple 3-wire unidirectional serial bus is used for programming the IC. The lines are called DATA, CLK and EN (enable). Programming data is sent to the IC in bursts which are separated from each other by EN. Programming clock edges are ignored until EN goes active LOW. The data is loaded into the addressed register when EN returns inactive HIGH, and when the CLK is in either state, without affecting the data in the register. The register only holds the last 18 bits that are serially clocked into the IC. RECEIVER POWER STATUS CONTROL • DC offset compensation: This feature allows the DC offset of the receiver output to be set accurately. When the receiver is on, the LNA can be switched off to isolate the antenna input from the I/Q demodulator input. The offset at the I and Q outputs can be independently reduced to less than 50 mV by adequately programming two 5-bit data registers, see Table 4 “Register bit allocation”. The LNA is switched on or off by the status of bit LNA (see Table 2). Additional leading bits are ignored, and no check is made on the number of clock pulses received. The fully static CMOS design uses virtually no current when the bus is inactive. It can always accept new programming data even when both synthesizers are powered-off. • Disabling RF section: For DCS applications, the RF section can be disabled in RX mode. The same IF circuits are used for both GSM and DCS applications to avoid duplication. For DCS applications using the UAA2077XM, for example, the RF section of the UAA3522HL does not have to be powered on. The RF section is enabled or disabled by the status of bit RF when the RX mode is activated (see Table 3). 2000 Feb 18 Bit RF status DATA FORMAT Data is loaded into the register with the most significant bit (MSB) first. The first 14 bits are data, while the last 4 bits are the register address. The address bits are decoded on the rising edge of EN. This internally generates a load pulse to store the data in the addressed register. To ensure that data loads correctly after the device has powered-up, EN should be held LOW and only taken HIGH after the appropriate register has been loaded. The EN pulse is inhibited during the period when data is read by the frequency dividers to prevent divider ratio data from being read incorrectly. This state is guaranteed by always allowing for a minimum EN pulse width after data transfer. 8 This text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here in _white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader.This text is here inThis text is here in white to force landscape pages to be rotated correctly when browsing through the pdf in the Acrobat reader. white to force landscape pages to be ...

SOLDERING Introduction to soldering surface mount packages • For packages with leads on four sides, the footprint must be placed at a 45° angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our “Data Handbook IC26; Integrated Circuit Packages” (document order number 9398 652 90011). During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. There is no soldering method that is ideal for all surface mount IC packages. Wave soldering is not always suitable for surface mount ICs, or for printed-circuit boards with high population densities. In these situations reflow soldering is often used. Typical dwell time is 4 seconds at 250 °C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. Several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. Typical reflow peak temperatures range from 215 to 250 °C. The top-surface temperature of the packages should preferable be kept below 230 °C. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. If wave soldering is used the following conditions must be observed for optimal results: • Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. • For packages with leads on two sides and a pitch (e): – larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; – smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. 2000 Feb 18 UAA3522HL 25 Philips Semiconductors Objective specification Low power dual-band GSM transceiver with an image rejecting front-end UAA3522HL Suitability of surface mount IC packages for wave and reflow soldering methods SOLDERING METHOD PACKAGE REFLOW(1) WAVE BGA, LFBGA, SQFP, TFBGA not suitable suitable(2) HBCC, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, SMS not PLCC(3), SO, SOJ suitable LQFP, QFP, TQFP SSOP, TSSOP, VSO suitable suitable suitable not recommended(3)(4) suitable not recommended(5) suitable Notes 1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”. 2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
