450MHz CDMA/OFDM LNA/Mixer
General Description
The MAX2335 RF front-end receiver IC is designed for
CDMA and OFDM applications in the 450MHz band.
The MAX2335 includes a low-noise amplifier (LNA) with
adjustable IIP3 to minimize desensitization due to cross-
modulation in the presence of a large interfering signal.
The mixer features differential IF outputs and is
designed for high linearity and low noise, which is well
suited for CDMA and OFDM applications.
An on-chip frequency divider is included to allow the
use of a standard 1GHz VCO. Alternatively, the divider
can be bypassed for use with a lower-frequency VCO.
The MAX2335 is available in a 28-pin TQFN package
with exposed paddle and is specified for the -40°C to
+85°C extended temperature range. The device is also
offered in a lead-free package.
