APPLICATION OF HIGH POWER OUTPUT MULTIPLEXERS FOR COMMUNICATIONS SATELLITES

This paper describes the development and qualification of high power dielectric multiplexers at C-band and Lband for commercial satellite applications. New packaging techniques and the employment of the single mode dielectric filter configuration has simplified fabrication and tuning while reducing mass and volume by more than 40% and has improved RF performance over existing TE111 dual mode Invar technology. It has been demonstrated that the use of dielectric technology in output multiplexers offers an alternative solution to reduce size and mass of such equipment.
