Abstract
The present invention provides a new architecture for MMIC circuitry that allows reception of electronically selectable single polarity for simultaneous dual polarity/dual beam signals by phased-array modules. Additionally, an improved phase shifter design that is smaller and requiring fewer electronic components than prior art phase shifters is disclosed. In particular, the phase shifter requires only a single control line for each stage of the phase shifter.
