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 sup-
ports 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 compromising performance.
The IC includes: four LNA’s for multi-band support; an integrated voltage controlled
oscillator (VCO); automatic gain control (AGC); a quadrature downconverting mixer;
and, low and high band transmit buffers. Chip functionality, including IF AGC set-
ting, is controlled through a three-wire serial data interface (SDI). The RF2722 is
part of the POLARIS^TM TOTAL RADIO^TM solution.
