front-end. The IC contains all of the required components

to implement the RF functions of the receiver except for

the passive filtering and LO generation. It contains an

LNA (low-noise amplifier), a second RF amplifier, and a

balanced mixer which can drive a single-ended or bal-

anced load. The output of the LNA is made available as a

pin to permit the insertion of a bandpass filter between

the LNA and the RF/Mixer section. The LNA output is

buffered to permit a wide range of choices for the inter-

stage filter without altering the VSWR or noise figure at

the LNA input and to provide high isolation from the LO to
