Datasheet
Ultra-linear Mixer with Integrated IF Amp and LO Buffer
Description
CMY212 is a general purpose down-converter
device designed for multiple applications such
as cellular and PCS mobile phones, ISM
bands, GPS receivers, L-band satellite
terminals, WLAN and pagers. Due to its
excellent intermodulation characteristics and
its high conversion gain, CMY212 is
particularly suited for CDMA receiver
applications.
The device combines an ultra-linear mixer
with LO - driver and a single stage IF-amplifier
in a very small SCT598 package. The mixer
section of CMY212 combines low conversion
losses and excellent intermodulation
characteristics with low requirements of LO -
and DC-power. The internal level controlled
LO-Buffer enables a good performance over a
wide LO level range. The input and output
matching of the IF amplifier can be adapted
externally within a frequency range from 45 to
250 MHz.
