RF2628 6 Typical Applications • CDMA/FM Cellular Systems • Supports Dual-Mode AMPS/CDMA • Supports Dual-Mode TACS/CDMA • Commercial and Consumer Systems • Battery-Operated Systems CDMA/FM UPCONVERTER/BPSK MODULATOR Product Description The RF2628 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 operates at a supply voltage of 2.7V to 5.
