A power signal combining apparatus for a transmitter

The invention discloses a power signal combining apparatus for a transmitter, can solve the problem that a microstrip combiner inside a traditional power combiner can only be used in small power combining because of twothin copper skin and low power bearing capacity of a trnamsision line, and a cavity combiner inside the power combiner can bear relatively large power, but has defects of no isolation, reverse standing wave difference and the like. The power signal combining apparatus comprises a tapered outer conductor, a tapered inner conductor, a cylindrical outer conductor, an inner separated curved surface conductor, an output terminal and four input terminals, one end of the cylindrical outer conductor is electrically connected with the four input terminals, the other end of the cylindrical outer conductor is connected with the tapered outer conductor, and an output terminal is arranged on the tapered outer conductor. In work, four paths of power signals are electrically connectedwith the separated curved
