Description

Ideal Front-End Filter for European Wireless Receivers Low-Loss, Coupled-Resonator Quartz Design Simple External Impedance Matching Rugged TO39 Hermetic Package Complies with Directive 2002/95/EC (RoHS)

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 conserve 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 output. IF matching is external to the module.
