PHASED ARRAY ANTENNA FEED

摘要

An RF signal receiving/transmitting apparatus for use with a phased array antenna having a plurality of antenna elements comprises a plurality of signal processing circuits, each circuit being connected to and associated with one of the antenna elements and including a signal distributing/combining device connected to its associated element, a plurality of sampling gates for spatially sampling a distributed signal or applying analog samples to the distributing/combining device, and analog-to-digital or digital-to-analog converters connected to an analyzer for analyzing/generating a plurality of digital samples which are received or to be transmitted by the antenna elements.
