High Power Combining of Ka-Band TWTs for Deep Space Communications
Abstract
This paper presents the results of a high efficiency power combining demonstration of two 100 W Ka-band space TWTs using a 4-port magic-T hybrid junction-based waveguide circuit. Power combining efficiencies of about 90% over a 1 GHz frequency band centered at 32.05 GHz and a high data transmission rate of 622 Mbps were successfully demonstrated.
