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 demodulation immunity • Single +3.0 V supply • RFLGA™ (32 pin, 5 x 5 mm) Pb-free package (MSL3, 260 °C per JEDEC J-STD-020) GND GND GND GND 27 I+ I– RF+ RF– 0 90 180 LO GND GND GND VCC VCC VCC GND GND GND 1 2 3 4 5 6 7 8 9 32 31 30 29 28 26 GND 25 24 23 22 21 20 19 18 17 RF+ RF– GND IFIP GND IFIN GND IFQP GND IFQN GND C1468 10 11 12 13 14 15 16 GND GND GND GND LO GND Q+ Q– C1469 Figure 1.
