Abstract(in English) | A high power transmitter frequently consist of two or more amplifiers, and outputs of the amplifiers are combined by a power combiner. However, when some amplifiers stop, an insertion loss of the power combiner increases because the number of the input powers vary. In this paper, a power combiner allowing for the variable number of input ports is presented. The proposed power combiner is a tournament-shaped combiner in which lengths of lines between T junction circuits are an odd multiple of a 1/4 wavelength. When some amplifiers stop, the powers of each amplifier can be combined with low loss in the proposed combiner, because the lines between the T junction circuits operate as impedance transformer.. The proposed 8 combiner is simulated and experimentally demonstrated in S-band. The insertion loss at six amplifiers is 0.25 dB in the experiments. |
