Pcs Upconverter/bpsk Modulator

The RF9938 is a complete upconverter designed for PCS applications. The IC contains a double-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 resis- tors 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 3.6V and is designed as part of the RFMD PCS CDMA Chip Set, consisting of a Transmit IF AGC Amp, this Transmit Upconverter, a Receive LNA Mixer, and a Receive IF AGC Amp.
