REP003, Cellular Front-End IC in Automobile Application
Referenzdesign von: Analog Devices
REP003, Reference design (RD) is for a dual-band CDMA frontend IC for use in automotive applications. The application circuit uses the MAX2323 low-noise amplifier (LNA) with mixer at temperatures up to 110°C. The device 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, which improves switchover hysteresis margin
