The RF9957 is an integrated complete IF AGC amplifier
and Quadrature Demodulator designed for the receive
section of dual-mode CDMA/FM cellular and PCS appli-
cations. It is designed to amplify received IF signals, while
providing 100dB of gain control range, and demodulate to
baseband I and Q signals. Noise Figure, IP
3
, and other
specifications are designed to be compatible with the IS-
98 and J-STD-018 Interim Standard for CDMA cellular
communications. The IC is manufactured on an advanced
15GHz F
T
Silicon Bipolar process, and is packaged in a
standard miniature 24-lead plastic SSOP package.
