RF System with an RFIC and Antenna System

摘要

In accordance with an embodiment, a packaged radio frequency (RF) circuit includes a radio frequency integrated circuit (RFIC) disposed on a substrate that has plurality of receiver circuits coupled to receive ports at a first edge of the RFIC, and a first transmit circuit coupled to a first transmit port at a second edge of the RFIC. The packaged RF circuit also includes a receive antenna system disposed on the package substrate adjacent to the first edge of the RFIC and a first transmit antenna disposed on the package substrate adjacent to the second edge of the RFIC and electrically coupled to the first transmit port of the RFIC. The receive antenna system includes a plurality of receive antenna elements that are each electrically coupled to a corresponding receive port.
