The present invention is achieved through the following technical solutions：
A kind of wideband high-power synthesizer, including input power combing transformer, input power combing transformer connect
Output end impedance conversion transformer is connected to, the input power combing transformer includes magnetic core, and it is same to have passed around radio frequency on magnetic core
Shaft cable a and radio frequency coaxial-cable b, polyfluortetraethylene pipe is cased with outside two radio frequency coaxial-cables；
Radio frequency coaxial-cable a and radio frequency coaxial-cable b is connected with the first input printed board, the second input printed board and work(
Rate synthesizes printed board；Two-way input signal is connected with input power combing transformer, two-way input signal passes through respectively
One input printed board connects two radio frequency coaxial-cables with the second input printed board；Power combing printed board is by the signal after synthesis
It is transferred to output end impedance conversion transformer；
Input balance resistance plate is connected between the two-way input signal.
Further improve, the first input signal in the two-way input signal is connected with by the first input printed board and penetrated
One end of high frequency coaxial cable a inner wires and one end of radio frequency coaxial-cable b outer conductors；Radio frequency coaxial-cable a inner wires and radio frequency
The other end connection power combing printed board of coaxial cable b outer conductors；
The second input signal in two-way input signal is connected with radio frequency coaxial-cable b by the second input printed board to be led
One end of body and one end of radio frequency coaxial-cable a outer conductors；Radio frequency coaxial-cable b inner wires and radio frequency coaxial-cable a outer conductors
