MAX2323EGI-MAX2325EGI
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 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.

DC ELECTRICAL CHARACTERISTICS

(VCC= +2.7V to +3.6V, RRBIAS= 20kΩ, RRLNA= 24kΩ, TA= -40°C to +85°C, no RF applied. Typical values are VCC= 2.75V and
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

AC ELECTRICAL CHARACTERISTICS

(MAX2323 EV kit, FPLNAIN= 1960MHz, FCLNAIN= 881MHz, FIF= 110MHz, high-side LO, 50Ωsystem, RRBIAS= 20kΩ,
RRLNA= 24kΩ. Typical values are VCC= 2.75V, TA= +25°C. LO input power = -7dBm, LOW = 0V, HIGH = VCC, unless otherwise
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 ±3σfrom 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. ICCfor all LNAs (except HGHL) and mixers are inversely proportional to RRBIAS.
IIP3 can be traded for ICCby selecting other values of RRBIAS.
