The CX74036 embodies all the necessary functions for a radio receiver system except for the RF and Intermediate Frequency (IF) filters and RF Local Oscillator (LO) sources. The device front-end section has two Low Noise Amplifier (LNA) and mixer pairs, one for the 800 MHz band and the other for the 1900 MHz band. A common path is taken from the first IF mixer output to the demodulator output.
