Research on Design of Odd Power Synthesis Based on Hybrid Circuits

Power synthesis has always been one of the key technologies in power amplifier design, for the unused frequency bands and power requirements, the circuit form and synthesis method of power synthesis can be realized are obviously different, this paper designs a wideband power synthesizer covering the frequency range of 6-18GHz, using the mixed integration of odd bond line circuit and even waveguide to achieve multi-channel power planar synthesis, in which even waveguide synthesis uses improved side feed-time HT mode transmission, reduce the volume, while guaranteeing transmission performance. The simulation and physical tests show that its input standing wave is better than 1.8 and the average insertion loss is less than 2.0dB, to meet the design requirements. The synthesizer is designed to support higher-power UWB power amplifiers.
