3.0-MILLIMETER WAVELENGTH DUPLEXER
Abstract
I DENTIFIERS: Crystal protector. The 3.0-millimeter wavelength duplexer program concerns the development of two gas switc ing devices for rec iver protection over a frequency band of 91 to 96 kmc. One tube is a dual TR tube for use in a balance duplexer and the other tube is a crystal protector. The balanced duplexer shall operate at peak power levels of at least 10 kw and a duty cycle of 0.0005 while the crystal protector shall provide receiver crystal protection from peak power levels from 50 milliwatts to 1000 watts at a 0.0005 duty cycle. Both tubes will be built in RG-99 rectangular waveguide. The crystal protector tube will mate with UG387/U cover flanges since the related microwave components are presently being developed in this waveguide size, while the dual TR tube will mate with the flanges on the TRG 3-db hybrid couplers. A study program will be conducted in parallel with tube development to investigate the methods and the problems associated with duplexing in circular waveguide. (Author)
