Abstract

A proof-of-concept (POC) X-band active phased-array antenna was developed and fabricated to demonstrate the technology for potential use in future Defense Satellite Communication System satellites. The eight-element POC subarray was capable of producing two simultaneous independent beams using an MMIC-driven beam-forming matrix. A 2-W SSPA preceded every radiating element to produce the required EIRP. The design of the complete phased array to satisfy system requirements is discussed, and measured results for the array, including intermodulation patterns and bit error ratio response, are presented
