Abstract
A device for measuring a multipactor effect in microwave systems includes a first coupler, a vacuum enclosure where a sample under test is enclosed, and a second coupler, all in series between an input which receives incident power and an output which delivers output power. The device also includes a mixer operated as a phase detector having a first input connected to an output of the first coupler to sample part of the input power via a first attenuator and a phase-shifter and a second input connected to an output of the second coupler to sample a part of the output power via a second attenuator. The output of the mixer is connected to a noise measuring device.
