LOW NOIS E AMPLIFIER/MIX ER MODULE
CDMA Cellular/PCS Handsets
The RF3404 is a fully-functional, integrated dual-band
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
VCO. Multiple gain control options are available to con-
serve current and meet IS-98B specifications. The mixer
design allows for a common IF filter for CDMA cellular
and PCS operation, and a second output for the FM out-
put. IF matching is external to the module.
