CDMA/FM UPCONVERTER/BPSK MODULATOR
Product Description
The RF9908 is a complete upconverter designed for CDMA/FM cellular 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 IP3.
The output stage is a class-B, push-pull configuration to reduce the overall current and still provide a good 50 Ω output match.
The unit ope...
