Abstract

Disclosed is a circuit for switching a microwave output signal over to a first or a second output. The circuit has: two amplifiers receiving, at input, two parts, substantially equal in power, of an input signal, a coupler having two inputs connected to the outputs of the amplifiers and two outputs forming the outputs of the switching circuit, controllable phase-shifting means to place the signals injected at input of the coupler in phase or in phase opposition and to obtain the output signal sometimes at one output of the coupler and sometimes at the other output. The device can be applied to antenna switching circuits.
