US Patent 11199616 Configurable beam former integrated circuit and method

Systems and methods relate to a configurable integrated circuit for beamforming. The integrated circuit includes a first beam transmit input, a first beam receive output, a second beam transmit input, a second beam receive output, a first antenna terminal, a second antenna terminal, a first switched combiner, and a second switched combiner. The first switched combiner includes a first combiner input/output coupled to the first antenna terminal, a first combiner output coupled to a first output path having a first branch coupled to the first beam output and a second branch coupled to the second beam output, and a first combiner input coupled a first input path having a third branch coupled to the first beam input and a fourth branch coupled to the second beam input.
