General Description and Notes for CMY 212
CMY 212 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, CMY 212 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 SCT-598-8-1 package. The mixer section of CMY 212 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.
