Research on the power combining efficiency of a shipborne X-band transmitter
A power combining solution using magic-T is presented to apply in a shipborne X-band transmitter. According to scatter parameter theory, the factors that have influence on combining efficiency are analyzed; the combining efficiency and max output power are calculated. The results show that: (1) the magic-T has the advantage of small size, simple structure, good heat dissipation performance, so that it suits the shipborne situation well. (2) The combining efficiency of magic-T depends mostly on the insertion loss, and the amplitude and phase of input signal. (3) The 1kW output can be satisfied using the power combining solution presented.
