KU- BAND TEMPERATURE COMPENSATED HIGH POWER MULTIPLEXERS

COM DEV has developed a new generation of temperature compensated Ku-band output multiplexers offering significant size, mass, power handling and RF performance improvements over existing technologies. Changing the base material of the filters to Aluminum, from the more conventional Invar, greatly reduces mass, while improving the heat transfer from the filter to the spacecraft. COM DEV’s unique temperature compensation technique ensures superior RF performance of the Aluminum filter by reducing the equivalent linear frequency drift, (ELFD), to less than one ppm/C. This paper presents an overview of the design and the results of the qualification testing carried out by COM DEV.
