Abstract :
Raytheon developed two advanced C-band (5.05-5.09 GHz) phased arrays (AZ and EL antennas) having 1 deg beamwidths for CAT III MLS applications for the FAA. The antennas were developed by Interscan under a subcontract to Raytheon. Raytheon developed the MMIC phase shifters, beam steering architecture, monitoring, mechanical interfaces and frangible shelter. Significant features of these antennas include invar support structure, frangibility, wind isolation shelter, integral and near field monitoring, bit wiggle calibration, and phase cycling
