The RF2667 is an integrated complete IF AGC amplifier
and quadrature demodulator developed for the receive
section of dual-mode CDMA/FM cellular and PCS appli-
cations and for GSM/DCS and TDMA systems. It is
designed to amplify received IF signals, while providing
100dB of gain control range, and demodulate to base-
band I and Q signals. Noise figure, IP
3
, and other specifi-
cations are designed to be compatible with the IS-98, and
J-STD-018 Interim Standard for CDMA cellular communi-
cations. This circuit is part of the RFMD line of complete
solutions for digital radio applications. The IC is manufac-
tured on an advanced 15GHz F
T
Silicon Bipolar process,
and is packaged in a standard miniature 24-lead plastic
QSOP package.
