Beamforming integrated circuit having RF signal ports using a ground-signal transition for high isolation in a phased antenna array system and related methods

摘要

A phased antenna array system is provided that includes a beamforming integrated circuit and beamforming elements in communication with the integrated circuit disposed on a substrate. The beamforming integrated circuit includes multiple radio frequency (RF) signal ports. One or more of the RF signal ports includes an RF signal pad disposed between an edge of the integrated circuit and an internal RF ground pad. The RF signal pad and the internal RF ground pad of the RF signal port are oriented perpendicular with respect to the edge of the integrated circuit. Specifically, the RF signal pad has a first side disposed on or adjacent to the edge of the integrated circuit and an opposing second side that is adjacent to the internal RF ground pad. A method of controlling the phased antenna array system is also provided.
