Product Description

The RF2619 is a complete AGC amplifier designed for

the transmit section of 3V dual-mode CDMA/FM cellular

applications. It is designed to amplify IF signals while pro-

viding more than 84dB 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 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 16-lead plastic SSOP

package.
