RF2628 General Description
The RF2628 is a complete upconverter designed for CDMA/FM cellular applications. The IC contains a dou-ble-balanced mixer stage and an output buffer amplifier stage. This device may also be used to directly BPSK modulate a carrier. The mixer is a Gilbert cell with emitter degeneration resistors to provide high IP3 . The output stage is a class-B, push-pull configuration to reduce the overall current and still provide a good 50 output match.
The unit operates at a supply voltage of 2.7V to 5.0V and does not require any external matching components other than coupling capacitors. This circuit is designed as part of the RFMD CDMA Chip Set, consisting of a Trans- mit IF AGC Amp, this Transmit Upconverter, a Receive LNA/Mixer, and a Receive IF AGC Amp.

RF2629 General 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.
