Abstract
A phased-array transmitter and receiver that may be effectively implemented on a silicon substrate. The transmitter distributes to front-ends, and the receiver combines signals from front-ends, using a power distribution/combination tree that employs both passive and active elements. By monitoring the power inputs and outputs, a digital control is able to rapidly provide phase and gain correction information to the front-ends. Such a transmitter/receiver includes a plurality of radio frequency (RF) front-ends and a power splitting/combining network that includes active and passive components configured to distribute signals to/from the front-ends.
