10 kW L-Band planar power combiner

[摘要] This thesis relates to the design and characterization of a 10 kW L-band power combiner consistingof 8 input ports. The design is implemented in a non-radial planar transmission linearchitecture and operates between 1.2 and 1.4 GHz.Because of the ultra high power requirements for the combiner, special attention is given to thepower handling capabilities of the transmission lines and the other components involved. SimulatedS-parameter models of connector to stripline transitions and a one to four-way junction,as well as measured S-parameter models of high power terminations are incorporated in thefinal design.A 10 kW combiner was built and measured at low power only due to time constraints and thelimited availability of high power sources. Satisfactory results were obtained in terms of thegraceful degradation of unit amplifiers, port mismatches and power combining efficiency.
