RF3404 - DUAL-BAND/TRI-MODE CDMA LOW NOISE AMPLIFIER/MIXER MODULE

General Description

The RF3404 is a fully-functional, integrated dual-band downconverter module for tri-mode CDMA applications.

Key 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. 0.6 2.
