Description

Conexant's CX74036 receive RF IC is an advanced, highly integrated and high performance, triple-mode, dual-band IC for IS-136 compliant cellular radio applications and is designed in an advanced 28 GHz Ft BiCMOS process. In the 800 MHz cellular band, the CX74036 is designed to operate in both the Time Division Multiple Access (TDMA) mode and Advanced Mobile Phone System (AMPS) mode. In the 1900 MHz Personal Communications System (PCS) band, the device operates in the TDMA mode.

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.

The CX74036 48-pin, 7x7 Land Grid Array (LGA) package pin configuration is shown in Figure 1. A block diagram of the CX74036 is shown in Figure 2
