www.DataSheet4U.com DATA SHEET SKY73012: 400 – 3900 MHz Direct Quadrature Demodulator Applications WiMAX (802.16) receivers CDMA macro and pico base stations 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) RFID readers Description Skyworks SKY73012 is an integrated, broadband, high-dynamic range quadrature demodulator for use in various wireless communication system applications. The SKY73012 can perform quadrature demodulation of RF input signals from 400 to 3900 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 SKY73012 make it ideal for use in direct conversion and low Intermediate Frequency (IF) receivers. Figure 1 shows a functional block diagram for the SKY73012. 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 3900 MHz) Wideband LO input frequency range (400 to 3900 MHz) Integrated LO balun Integrated LO amplifier On-chip I/Q phase splitter Differential IF output supports direct interface to A/D circuitry AM ...
