downconverter module for tri-mode CDMA applications.
The module, which uses SiGe technology, features two
complete RF downconverters with low noise amplifiers,
RF SAW filters, TX LO buffers, and RF matching for PCS
and cellular band frequencies. Additionally, a divide-by-2
prescaler is integrated to allow the use of a single-band
