GSM/GPRS/EDGE RECEIVER
Part of the POLARISTM TOTAL RADIOTM Solution
RoHS Compliant & Pb-Free Product
Typical Applications
• EGSM/DCS Handsets
• EGSM/DCS/PCS Handsets
• GSM850/PCS Handsets
• GSM850/EGSM/DCS/PCS Handsets
Product Description
The RF2722 is a highly-integrated receiver IC supporting
GSM, GPRS, and EDGE cellular standards in the
GSM850, EGSM, DCS, and PCS bands. The RF2722
supports both very-low intermediate frequency (VLIF) as
well as direct conversion receive (DCR) architectures,
reducing external component count and eliminating the
need for IF SAW and RF interstage filters without com-
promising performance. The IC includes: four LNA’s for
multi-band support; an integrated voltage controlled oscil-
lator (VCO); automatic gain control (AGC); a quadrature
downconverting mixer; and, low and high band transmit
buffers. Chip functionality, including IF AGC setting, is
controlled through a three-wire serial data interface (SDI).
The RF2722 is part of the POLARISTM TOTAL RADIOTM
solution.
