www.DataSheet4U.com PRODUCT SUMMARY SKY74693: Receiver for CDMA, AMPS, PCS, and GPS Mobile Handset Applications Applications • Tri-band, tri-mode handsets • PCS and GPS phones • CDMA and GPS phones Except for the Surface Acoustic Wave (SAW) filters, a UHF Voltage Controlled Oscillator (VCO), and matching components, the device incorporates everything required to implement the receiver chain, from the Low-Noise Amplifier (LNA) to the In-Phase and Quadrature (I/Q) demodulator stages. Three LNAs are in the frontend receiver: a three-step gain stage cellular LNA (high, mid, and bypass), a two-step gain stage PCS LNA (high, bypass), and a high gain stage GPS LNA. After RF LNA signal amplification and filtering from the antenna, the received signal is mixed down from RF to the IF.
