Structure design and verification of spaceborne ka-band channel synthesis multiplexer components

Abstract

A method for the structural design of a Ka channel synthesis multiplexer is proposed in accordance with the footprint area, weight, natural frequency, and mechanical environment adaptability requirements of the space-borne equipment. This design utilizes key U-type folded design methods, in which two Ka channel synthesis multiplexers are cross-folded onto an integrated structural frame to reduce the equipment layout area to 33.6% of the original plane layout. Mechanical analysis and ground tests are utilized to verify the correctness and rationality of the Ka channel synthesis multiplexer structure design. This structural design concept for the Ka channel synthesis multiplexer provides a reference for the structural design of similar spaceborne equipment.
