Abstract : The objectives of this development program on a miniaturized X-band stripline duplexer are discussed in relation to the present state-of-theart. General approaches to the problem are outlined. The various major elements of the duplexer are discussed and the method of approach to the solution of each pertinent problem is analyzed. A broadband waveguide-to-stripline transition has been developed covering the frequency range of 9,200 to 9,700 megacycles. An experimental fixture has been constructed for the convenient testing of limiter modules. This fixture utilizes the broadband waveguide-tostripline transition mentioned previously. A test fixture has been designed to evaluate the ferrite circulator module. Various transmission line configurations and a limited number of ferrite materials have been investigated. Studies are also underway on the development of a broadband TNC-to-stripline transition and a broadband directional coupler covering the 9,000 to 10,000 megacycle band. Preliminary experimental results show promise.
