3V CDMA/FM RECEIVE AGC AMPLIFIER
• General Purpose Linear IF Amplifier
• Commercial and Consumer Systems
• Portable Battery Powered Equipment
Product Description
The RF2617 is a complete AGC amplifier designed for
the receive section of 3V dual-mode CDMA/FM cellular
applications. It is designed to amplify IF signals while pro-
viding more than 90dB of gain control range. Noise Fig-
ure, IP3, and other specifications are designed to be
compatible with the IS-95 Interim Standard for CDMA cel-
lular communications. This circuit is designed as part of
the RFMD CDMA Chip Set, consisting of a Transmit IF
AGC Amp, a Transmit Upconverter, a Receive LNA/Mixer,
and this Receive IF AGC Amp. The IC is manufactured on
an advanced high frequency Silicon Bipolar process, and
is packaged in a standard miniature 16-lead plastic SSOP
package.
