Microwave power combination using a bifurcated waveguide and a reflecting plate

The coupling circuit is constructed of a bifurcated rectangular waveguide which is especially suitable for high-power combination. In this circuit, there is a thin conductor plate perpendicular to the E plane which acts as a reflector only for higher modes, so that the reflected wave is injected back into oscillators for mutual synchronization. Both analytical and experimental results show that a maximum power-combining efficiency near 100% is achievable.<
