Triple/Dual-Mode
CDMA LNA/Mixers
____________________________Features
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.
♦ 2.7V Operation
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. For the other
gain states, the LNA current is reduced to improve standby 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.

Note 1: Devices are production tested for functionality at frequencies stated; 30 units from 3 independent wafer lots, when one lot
was at the upper process extreme, one lot was nominal, and one lot was at the lower process extreme, were characterized.
The resulting standard deviation therefore includes process variations. Data sheet limits are ±3σ from the mean.
Note 2: Operation over this frequency range requires the ports to be rematched for the desired operating range. Performance at
various frequencies is indicated by the S-parameter data in Tables 3–7.
Note 3: Specifications are based on RBIAS = 20kΩ. ICC for all LNAs (except HGHL) and mixers are inversely proportional to RRBIAS.
IIP3 can be traded for ICC by selecting other values of RRBIAS.
