The Development of a Ka Band Input Filter Assembly for a Satellite Transponder

Abstract:

This paper presents the development of a Ka band Input Filter Assembly(IFA) with very low insertion loss and a high temperature stability suitable for a communication satellite transponder. The IFA consists of a cross directional test coupler to check the input signal level of the transponder and an input filter to pass the uplink band signals. The test results show good agreement with the simulation and compliant to the requirements with the temperature range from –20 °C to 60 °C. This IFA will be used for the communication satellite in Korea.
