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.
