SKY73009-11 Block Diagram Differential IF output supports direct interface to A/D circuitry AM demodulation immunity Description Single +3.0 V supply The SKY73009-11 is an integrated, broadband, high-dynamic RFLGA (32-pin, 5 x 5 mm) package range quadrature demodulator for use in various wireless (MSL3, 260 C per JEDEC J-STD-020) communication system applications. The SKY73009-11 can perform quadrature demodulation of RF input signals from 400 to 3000 MHz directly to baseband frequencies. The quadrature TM Skyworks Green products are compliant with outputs are differential and can be directly connected to most all applicable legislation and are halogen-free. commonly available A/D converters. For additional information, refer to Skyworks The high dynamic range and second order input intercept point TM Denition of Green , document number (IIP2) value of the SKY73009-11 make it ideal for use in direct SQ040074. conversion and low intermediate frequency (IF) receivers. Figure 1 shows a functional block diagram for the SKY73009-11. The device package and pinout are shown in Figure 2. Signal pins and descriptions are listed in Table 1. Skyworks Solutions, Inc.
