REP012, Cellular LNA Achieves +20dBm IIP3 in Low-Gain High-Linearity Mode

REP012, Reference design (RD) shows a dual-band, triple-mode CDMA front-end IC tuned to provide +20dBm in low-gain high-linearity mode. The RD features a CDMA low-noise amplifier (LNA) that 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
