www.DataSheet4U.com DATA SHEET SKY73009: 400 – 3000 MHz Direct Quadrature Demodulator Applications PCS, DCS, GSM/GPRS, and EDGE receivers Third Generation (3G) wireless communications Power amplifier feedback/linearization Wireless Local Loops (WLLs) Wireless Local Area Networks (WLANs) Description 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. 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. 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. Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances) compliant packaging. Features High IIP2 and IIP3 Wideband RF input frequency range (400 to 3000 MHz) Wideband LO input frequency range (400 to 3000 MHz) Integrated LO balun Integrated LO amplifier On-chip I/Q phase splitter Differential IF output supports direct interface to A/D circuitry AM demodulation immunity Single +3.0 V supply RFLGA™ (32 pin, 5 x 5 mm) Pb-fr...
