On the basis of previously carried out works [2, 3], it has been established that the most effective way for coherent summation of the power of two generators with a waveguide output is to use a waveguide 3-decibel bridge as an adder. In this case, the output power of the synchronized device within the synchronization band can reach 95% of the total power of the generators.

Purpose of the work is to describe the installation «microwave module», which uses the method of coherent summation of the powers of two magnetrons in the power adder.

Mutual phased synchronization of two magnetrons is provided by a phase shifter, matching is provided by a short-circuiting piston. The summed signal is sent to the output (antenna) path of the radar. The microwave generator module is designed to generate probing pulse signals in a multifunctional receiving-transmitting radar measuring complex.

For the first time in Russia, JSC «Pluton» has created a «microwave module» installation in the 2-centimeter wavelength range, which makes it possible to use the principle of coherent addition of the powers of two commercially available magnetrons. The installation cost and manufacturing time are many times less than those for a newly developed magnetron with the parameters presented in this article.
