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 appli-
cations by providing switched signal paths for cellular FM,
cellular CDMA, and PCS CDMA. The MAX2325 is a cellu-
lar-band dual-mode version.
To optimize cellular-band dynamic range at minimum cur-
rent, 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. For the other
gain states, the LNA current is reduced to improve stand-
by time.
The CDMA mixers are designed for high linearity, low
noise, and differential IF outputs, while the FM mixer is
designed for lower current and single-ended output. Each
band is implemented with a separate mixer to optimize
performance for the specific band.
The MAX2323/MAX2325 can also be used in TDMA,
EDGE, and W-CDMA phones.
