Abstract :
Optical distribution of control signals in electronically steered phased array antennas is considered. A demonstration experiment in which a high-speed hybrid GaAs optoelectronic integrated circuit (OEIC) was used to control a 28.2 GHz eight-element phased-array antenna is described. The OEIC, which accepts a serial optical control signal as input and converts it to 16 demultiplexed parallel outputs, was used to control the monolithic GaAs phase shifters of a Ka-band patch panel array antenna. Antenna pattern switching speeds of 2.25 mu s, limited by interface circuitry, were observed.<>
