19-1736; Rev 0; 7/00 Triple/Dual-Mode CDMA LNA/Mixers ________________General Description The MAX2323/MAX2325 are low-noise amplifier (LNA) plus mixer ICs optimized for code-division multiple-access (CDMA) applications in both cellular and PCS bands. The MAX2323 addresses dual-band, triple-mode CDMA applications by providing switched signal paths for cellular FM, cellular CDMA, and PCS CDMA. The MAX2325 is a cellular-band dual-mode version. To optimize cellular-band dynamic range at minimum current, the MAX2323/MAX2325 implement four LNA states: high gain/high linearity, high gain/low linearity, midgain, and low gain. In high-gain/high-linearity mode, the adjustable high-intercept LNA minimizes desensitization in the presence of a large interfering signal.
