Data Sheet April 1999 Description The W3030 is a monolithic integrated circuit that provides most of the receive path functions required to meet the IS-136 (and IS-54) standard. The W3030 converts FM or digitally modulated IF carriers up to 200 MHz and provides required IF gain and separate baseband detectors for the two modulation modes. The W3030 is organized into three subfunctions (see Figure 2): 1. First IF mixer/amplifier 2. Analog second IF 3. Digital second IF sections (Note that the electrical specification tables correspond to each subfunction.) Each section has a buffered output to allow for external filtering, which also provides flexibility in system architecture selection. The first IF mixer section provides 30 dB of fixed voltage conversion gain (power gain = 17 dB). The first IF mixer also performs down-conversion to the 0.2 MHz—2.0 MHz range, which allows the use of inexpensive ceramic filters at two points in the signal path. In the second IF section, the signal path may be split between two Lucent Technologies Inc. W3030 3 V Dual-Mode IF Cellular Receiver parallel amplifier/demodulator sections. In the analog second IF, there is a 40 dB amplifier followed by a 60 dB hard-limiting amplifier and an FM quadrature detector (noncoherent discriminator). The signal path between the 40 dB and 60 dB amplifier stages is brought off-chip for external filtering purposes. In digital mode, an AGC amplifier provides gain between 10 dB and 80 dB. The digital signal is demodulated in double-balanced mixers that are fed with an external local oscillator (LO) signal. The external LO passes through a divide-by-four counter to provide the final IF LO frequency. This architecture greatly reduces the possibility of feedback of the external LO signal to the IF input, which would cause dc offsets at the I & Q outputs. This circuit also provides a 90° phase shift of the LO that is independent of duty cycle. The resulting I & Q differential pairs can be level-shifted using the VCM input pin, providing flexibility in interfacing to digital processing ICs. A pair of logic inputs allows the device to be put into a powerdown mode and one of two partially enabled modes (analog or digital only), or a fully enabled mode, allowing the use of analog RSSI while in digital receive mode. 3 Data Sheet April 1999 W3030 3 V Dual-Mode IF Cellular Receiver 32 29 28 1 I I 22 Q Q AGC AMP I/Q DEMODULATOR 4 21 ENBA ANALOG SECOND IF LIMITER 5 20 ENBD FIRST IF MIXER/AMPLIFIER 10 MHz—1000 MHz 6 19 7 50 kΩ 18 SECOND IF AMP 0.2 MHz—2.0 MHz 8 17 IF1IN VCC1 11 12 13 14 15 16 IF1LO IF2OUT IF1IN 1 kΩ 2 kΩ 10 GND1 48 kΩ 9 IF2IN 1 kΩ IF2IN VCC2 CLK 48 kΩ 3 IF2ACG IFAIN 23 ÷4 1 kΩ IFAIN 25 24 2 50 kΩ IFAACG 26 50 kΩ 49 kΩ IFAOUT 27 FM DEMOD & RSSI 2 kΩ QUAD AGC VCM IFDACG 30 IF1LO AUDIO 31 IF1OUT RSSI IFDIN IFDIN GND2 Description (continued) Figure 2.

Lucent Technologies Microelectronics Group employs a human-body model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation. ESD voltage thresholds are dependent on the circuit parameters used to define the model. No industry-wide standard has been adopted for CDM. However, a standard HBM (resistance = 1500 Ω, capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold presented here was obtained by using these circuit parameters: W3030 ESD Threshold Voltage ESD Model Rating HBM ≥1500 V CDM ≥1500 V Lucent Technologies Inc. 7 Data Sheet April 1999 W3030 3 V Dual-Mode IF Cellular Receiver Operating Ranges Performance is not guaranteed over the full range of all conditions possible within this table.

Data Sheet April 1999 W3030 3 V Dual-Mode IF Cellular Receiver RSSI Quadrature Detector The RSSI output provides a voltage level that is proportional to the amount of signal present in the analog second IF section. This voltage level is generated internally by summing of the signal current at different points in the 40 dB and 60 dB IF chains. The amount of loss between the 40 dB and 60 dB sections will affect the RSSI linearity. Figure 3 contains two traces of RSSI voltage versus IF input power. One trace is with only the filter loss between the 40 dB and 60 dB amplifiers. The second trace is with a filter and a resistor, to give a total loss of 5.6 dB. The figure indicates a nonlinearity around the –75 dBm input level. This nonlinearity occurs because the 60 dB amplifier chain enters compression, causing less RSSI output. Eventually, as the input signal increases, the 40 dB amplifier will begin to contribute to the total RSSI. Figure 4 is a simplified schematic of the quadrature detector of the W3030. The quadrature detector circuit is similar to a mixer; but, instead of mixing two different frequencies, it multiplies two signals of the same frequency that are phase-shifted versions of each other. Multiplying the phase-shifted with the unshifted signals produces the audio portion of the FM signal. It was determined that 6 dB of interstage loss produces the optimal RSSI response. Most ceramic filters have less than 6 dB insertion loss. Therefore, some additional loss must be inserted in addition to the filter. The simplest way is to use a resistor in series with the filter. This method will cause a mismatch to the filter and may distort its passband response. An L or T configuration may be necessary to provide the required loss without mismatching the filter. ATTN 1.4 dB ATTN 5.6 dB 2.2 1.9 RSSI (Vdc) 1.6 IFAOUT CS AUDIO QUAD CP L R CBYPASS Figure 4. Quadrature Detector Before the IF signal is differentially applied to the multiplier, the signal is passed through a limiter stage to produce a constant amplitude signal. The same signal is brought out single-ended to pin 4, IFAOUT. The signal at IFAOUT is passed through a phaseshifting network (CS + CP + L + R). The phase-shifted signal is applied back to the lower portion of the multiplier at pin 3, QUAD. The parallel L/C resonant circuit provides frequency selective filtering at the IF frequency. The L/C tank must be ac-grounded at the IF frequency through a dc blocking capacitor (CBYPASS). Because information in an FM signal is contained in the deviation from the center frequency, the design of the resonant bandpass circuit is very important, particularly the load Q. A higher-loaded Q for a given deviation will produce a larger output signal than a lower Q circuit. However, a high Q circuit will permit only a limited amount of deviation from center frequency before distortion occurs. 1.3 1 0.7 0.4 –125 –115 –105 –95 –85 –75 –65 –55 –45 –35 –25 IF1IN POWER (dBm) Figure 3.

The Q of the tank circuit is set to 10 by the external resistor. Quad Tank S-Curves One method of determining if the Q of the tank is too large or too small is to produce an S-curve of the quad tank. An S-curve is a plot of the dc audio output voltage versus IF input frequency. With small deviations from center frequency, there is a proportional change in the dc audio output voltage. The overall linearity of the curve is determined by the Q of the tank circuit; therefore, the Q determines how much deviation is allowed before distortion of the audio signal occurs. The L/C tank circuit has a shunt resistor to set the Q of the tank. The procedure to produce these plots is as follows: 1. Remove the 450 kHz IF filter and drive the input of the limiting amplifier with a signal generator capable of FM modulation. 2. Apply FM modulation and adjust the tank capacitor for maximum audio out and minimal distortion. 3. Remove the FM modulation and sweep the IF frequency above and below center frequency while monitoring the dc voltage at the audio output. The following S-curves were produced with the value of the quad tank resistor varied from 18 kΩ, to 30 kΩ, to removing the resistor. The resistor value of 33 kΩ, which corresponds to a Q of 10, was chosen as the optimal resistor value. 12 Lucent Technologies Inc.
