The RF2628 is a complete upconverter designed for
CDMA/FM cellular applications. The IC contains a dou-
ble-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
3
. The output
stage is a class-B, push-pull configuration to reduce the
overall current and still provide a good 50
output match.
The unit operates at a supply voltage of 2.7V to 5.0V and
does not require any external matching components
other than coupling capacitors. This circuit is designed as
part of the RFMD CDMA Chip Set, consisting of a Trans-
mit IF AGC Amp, this Transmit Upconverter, a Receive
LNA/Mixer, and a Receive IF AGC Amp.
