A 2-kilowatt average power X-band receiver protector

A 2-kilowatt average power receiver protector with a 5,000-hour operating life has been developed. The design is of the gas plasma diode hybrid type which heretofore could provide only one-tenth the power handling for equivalent operating life. Predicted life is based on experimentally obtained molecular sorption coefficients performed at 2-kW average power in X-band. The device has been developed for use as a receiver protector in a high-resolution radar to be used at Lincoln Laboratory. This radar will transmit 200 kW average power at X-band and consequently requires a high average power receiver protector.
