The device incorporates all the components required to implement the receiver front end and the In-Phase and Quadrature (I/Q) demodulator stages except for the filter blocks and PCS Low Noise Amplifier (LNA). Besides a cellular band LNA, there are separate mixers for AMPS, CDMA 800 MHz, and PCS bands. The AMPS mixer output is single-ended, followed by the AMPS Intermediate Frequency (IF) Surface Acoustic Wave (SAW) filter. The cellular and PCS mixers have balanced outputs for the CDMA IF SAW filters. The mixers are followed by an IF Variable Gain Amplifier (VGA) and an I/Q demodulator.
