REP020, Dual-Band Dual-Mode FE IC with Common 210MHz IF

REP020, Reference design (RD) is for a dual-band, dual-mode CDMA front-end that uses a CDMA LNA/mixer, the MAX2323. The RD retunes the FM analog and the cellular/PCS digital mixers to 210MHz IF. This CDMA low-noise amplifier is also useful for TDMA, GSM, EDGE, and WCDMA applications. The MAX2323 low-noise amplifier (LNA) plus mixer is designed for dual-band CDMA cellular-phone handsets, but it can also be used in dual-band TDMA, GSM, EDGE, or WCDMA applications. It differs from its predecessor (the MAX2320) by adding a third (mid-gain) state for the cellular-band LNA that improves switchover hysteresis margin
