REP019, Tuned Dual-Band Front-End CDMA IC with Single 110MHz IF

REP019, Reference design (RD) assesses a tuned, dual-band, front-end CDMA IC with single 110MHZ IF. Focus is on the MAX2322, a low-noise amplifier (LNA) for dual-band CDMA cell-phone handsets. The MAX2323 can also be used in dual-band TDMA, GSM, EDGE, or 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
