• This paper presents the engineering verification of RF passive equipment for Communication, Ocean and Meteorological Satellite (COMS) to be launched in 2008. Those are the passive equipment for the input wide band filter, RF/IF channel filters, a manifold multiplexer, and a d iplexer. The objective of this engineering verification is to study the feasibility of those equipment to be applied to communication satellite. The input filter assembly (IFA) consists of a cross directional test coupler to check the input signal level of the transponder and an input band pass filter to pass the uplink band signals. Four-pole Chebyshev combline structure is chosen for the IF channel filter to reduce the mass and volume. RF channel filter and output multiplexer (OMUX) is used for the channelization of the frequency band into a number of RF channels. Dual mode technique is adopted in both 8-pole elliptic channel filters and 2-pole external equalizers for mass and volume reduction for RF channel filters. For low insertion loss, mass, and volume reduction, manifold type is employed for output multiplexer. E-plane waveguide T-junction of the diplexer with the inductive iris is used for a matching element to reduce the computation time for optimized performance. The inductive and capacitive irises are used for receiving and transmitting filter, respectively. The test results of all equipment show good agreement with the simulation results and are compliant to the requirement of each equipment. Followed by this verification, the flight model equipment will be developed for the COMS.
