3V CDMA/FM TRANSMIT AGC AMPLIFIER
Product Description
The RF2629 is a complete AGC amplifier designed for
the transmit section of 3V dual-mode CDMA/FM cellular
and PCS applications. It is designed to amplify IF signals
while providing more than 84dB of gain control range.
Noise Figure, IP3, and other specifications are designed
for CDMA and dual mode CDMA/AMPS handsets. This
circuit is designed as part of the RFMD CDMA Chip Set,
consisting of this Transmit IF AGC Amp, a Transmit
Upconverter, a Receive LNA/Mixer, and a Receive IF
AGC Amp. The IC is manufactured on an advanced high
frequency Silicon Bipolar process and is packaged in a
standard miniature 8-lead plastic MSOP package.
