Description:

RF/IF Converter/Synthesizer

Features

* a low noise, gain selectable ampliﬁer (LNA) followed by a down-converter mixer. An up-converter mixer and a high performance preampliﬁer compose the transmit chain. The remaining circuitry comprises a high frequency Phase Locked Loop (PLL) synthesizer with a three wire programmable interface for loc

Applications

* A reduced ﬁlter count is realized by multiplexing the receive and transmit IF paths and by sharing a common differential matching network. Furthermore, both transmit and receive RF ampliﬁers can be directly connected to mixers as bandwidth characteristics attenuate image frequencies. The inherent i
