RF9938 Datasheet (RF Micro Devices) - PCS UPCONVERTER/BPSK MODULATOR

RF9938, 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 resistors to provide high IP
