CDMA UPCONVERTER/BPSK MODULATOR
Product Description
The RF2641 is a complete upconverter designed for cel-
lular and PCS applications. This device may also be used
to directly BPSK modulate a carrier. The unit operates at
3.0V and is designed as part of the RFMD PCS/Cellular
CDMA Chip Set, consisting of a Transmit IF AGC Amp,
this Transmit Upconverter, a Receive LNA/Mixer, and a
Receive IF AGC Amp.
