RF2608
RF2608 is CDMA/FM UPCONVERTER/BPSK MODULATOR manufactured by RF Micro Devices.
Description
-A-
The RF2608 is a plete 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 5.0V and does not require any external matching ponents other than coupling capacitors. This circuit is designed as part of the RFMD CDMA chipset, consisting of a Transmit IF AGC Amp, this Transmit Upconverter, a Receive LNA/ Mixer, and a Receive IF AGC Amp.
