GENERAL DESCRIPTION

The ADMV4680 is a Ku frequency band, half-duplex beamforming

chip. The chip contains a single port network interface that is used

for both transmit and receive, a four-way splitter for both transmit

and receive, and a T/R switch to separate transmit and receive circuits.

A central digital controller allows the core chip to adjust gain

and phase of each channel. In a four-channel configuration, the

core chip receive path combines the four phase-adjusted signals

into a common RF port.
