The major effort on the program has been to develop a J band multipactor switch centered at 15 GHz. The desired device presents challenges with regard to high impedance circuitry, high secondary emission at low striking potentials, bandwidth, insertion loss, and very small spacing. Mundane challenges with stepped brazing techniques were presented by the use of Beryllium and Beryllium Copper secondary emitters and with processing to maintain secondary emission for good life of the unit. Not all of the challenges were met satisfactorily within the time and funding restrictions, and in fact there are most likely some challenges yet unrecognized. However, much progress has been made in understanding the dvices.
