In recent years, some waveguide traveling wave power synthesis amplifier structures had in succession been reported.This structure is vertically inserted multichannel coupled structure along the electromagnetic field direction of propagation of input waveguide, electromagnetic wave from input waveguide enters, in the process of propagating in turn RF power fed-in multichannel coupled structure.Utilize matching diaphragm simultaneously, while making in waveguide electromagnetic field propagate, in each coupled structure place areflexia, realize traveling wave.Coupled structure is connected with amplifier circuit, and the power after amplifying, again successively by coupled structure feed-in output waveguide, in the output of waveguide output port constant amplitude homophase, is realized power synthetic.This structure is expected to realize Ka wave band, and even more high band multichannel pmultiple amplifier is synthetic, realizes high-power output.Because being places amplifier array along row ripple direction, theoretically, this structure does not have the restriction of chip way, there is again the low-loss characteristic of waveguide simultaneously, therefore, utilize this structure to be expected to obtain high efficiency, high-power, compact conformation and be easy to the combining amplifier of heat radiation at the high-end and millimeter wave band of microwave.
