REP007, Cellular Front-End IC Drives IFR3100 IF Demodulator

REP007, Reference design (RD) shows how a dual-band, dual-mode CDMA front-end IC can drive an IRF3100 IF demodulator. The RD features the MAX2323 CDMA low-noise amplifier which 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. It also comes in a smaller package (28-QFN) and offers increased third-order
