DATA SHEET SKY73009: 400 – 3000 MHz Direct Quadrature Demodulator Applications Description • PCS, DCS, GSM/GPRS, and EDGE receivers Skyworks SKY73009 is an integrated, broadband, high-dynamic range quadrature demodulator for use in various wireless communication system applications. The SKY73009 can perform quadrature demodulation of RF input signals from 400 to 3000 MHz directly to baseband frequencies. The quadrature outputs are differential and can be directly connected to most commonly available A/D converters. • Third Generation (3G) wireless communications • Power amplifier feedback/linearization • Wireless Local Loops (WLLs) • Wireless Local Area Networks (WLANs) The high dynamic range and second order Input Intercept Point (IIP2) value of the SKY73009 make it ideal for use in direct conversion and low Intermediate Frequency (IF) receivers. Features • High IIP2 and IIP3 • Wideband RF input frequency range (400 to 3000 MHz) Figure 1 shows a functional block diagram for the SKY73009. The device package and pinout for the 32-pin RF Land Grid Array (RFLGA) are shown in Figure 2. • Wideband LO input frequency range (400 to 3000 MHz) • Integrated LO balun • Integrated LO amplifier Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances) compliant packaging. • On-chip I/Q phase splitter • Differential IF output supports direct interface to A/D circuitry • AM demodulation immunity • Single +3.0 V supply GND RF+ GND RF– GND GND 28 27 26 GND GND 2 24 IFIP GND 3 23 GND VCC 4 22 IFIN VCC 5 21 GND VCC 6 20 IFQP GND 7 19 GND GND 8 18 IFQN GND 9 17 GND 10 11 12 13 14 15 16 GND 25 GND LO 180 29 LO 90 30 GND RF+ RF– 31 1 GND 0 32 GND GND I– GND I+ GND • RFLGA™ (32 pin, 5 x 5 mm) Pb-free package (MSL3, 260 °C per JEDEC J-STD-020) C1468 Q+ Q– C1469 Figure 1.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal values. Equivalent Input Circuits An equivalent circuit for the RF input of the SKY73009 is shown in Figure 3. The equivalent circuit for the Local Oscillator (LO) input is shown in Figure 4. An internal balun is used to convert the single-ended LO input into a differential signal before being buffered inside the device. Electrical and Mechanical Specifications Signal pin assignments and functional pin descriptions are provided in Table 1. The absolute maximum ratings of the SKY73009 are provided in Table 2 and the recommended operating conditions provided in Table 3. Electrical characteristics of the SKY73009 are provided in Table 4. The typical performance of the SKY73009 with respect to frequency is illustrated in Figures 5 through 54. Figure 62 provides the package dimensions for the 32-pin RFLGA, and Figure 63 provides the tape and reel dimensions. Package and Handling Information Since the device package is sensitive to moisture absorption, it is baked and vacuum packed before shipping. Instructions on the shipping container label regarding exposure to moisture after the container seal is broken must be followed. Otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The SKY73009 is rated to Moisture Sensitivity Level 3 (MSL3) at 260 °C. It can be used for lead or lead-free soldering.

NF vs Frequency: 2300-2500 MHz (Murata LDB15C500A2400 Balun on RF Port) Evaluation Board Description The SKY73009 Evaluation Board is used to test the performance of the SKY73009 direct quadrature demodulator. There are three Evaluation Boards for this device, each configured for a specific frequency range. Schematic diagrams and Bills of Materials (BOMs) for each board are presented in the following Figures and Tables: • Figure 55 and Table 5 (800-1000 MHz) • Figure 56 and Table 6 (1500-2500 MHz) • Figure 57 and Table 7 (custom frequency) The Evaluation Board assembly diagram is shown in Figure 58 (800-1000 MHz), Figure 59 (1500-2500 MHz), and Figure 60 (custom frequency). Circuit Design Considerations The following design considerations are general in nature and must be followed regardless of final use or configuration. 1. Paths to ground should be made as short as possible. 2. The ground pad of the SKY73009 direct quadrature demodulator has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the device. As such, design the connection to the ground pad to dissipate the maximum wattage produced to the circuit board. 3. Two external output bypass capacitors are required on the VCC pin. The values of these capacitors will change with respect to the desired RF frequency. One capacitor should be used for low frequency bypassing and the other capacitor for high frequency bypassing. Special attention should be given 2400 2450 2500 Frequency (MHz) Frequency (MHz) Figure 54. NF vs Frequency: 2300-2500 MHz (Murata LDB15C500A2400 Balun on RF Port) so that the smaller value capacitor does not go into selfresonance at the desired RF frequency. 4. The RF input must be driven differentially. A 1:1 impedance ratio balun is recommended with a center tap on the secondary side that is DC grounded. Testing Procedure Use the following procedure to set up the SKY73009 Evaluation Board for testing. Refer to Figure 61 for guidance: 1. Connect a +3.0 VDC power supply using an insulated supply cable. If available, enable the current limiting function of the power supply to 100 mA. 2. Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of 0 dBm to the Evaluation Board but do NOT enable the RF signal. 3. Connect a signal generator to the LO signal input port. Set to the desired LO frequency at a power level of 0 dBm, but do not enable. 4. Connect a spectrum analyzer to the IFI signal output port and terminate the IFQ signal input port in 50 Ω. 5. Enable the power supply. 6. Enable the LO input signal. 7. Enable the RF signal. 8. Take measurements and repeat these steps for channel Q. CAUTION: If any of the input signals exceed the rated maximum values, the SKY73009 Evaluation Board can be permanently damaged.
