Description

The LORF9938 is a complete upconverter designed for PCS applications. The IC contains a double-balanced mixer stage and an output buffer amplifier stage. This LORF9938 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- push-pull configuration to reduce the overall current and still provide a good 50Ω 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 Receive IF AGC Amp.
