Abstract

Filtering device comprising a microwave band-pass filter with resonant cavities tunable by a single mechanical control shaft, an additional resonant cavity which is also controlled by this single control and which is tuned to a frequency shifted by a fixed value in relation to that of the other cavities, and a servocontrol mechanism for controlling the tuning of this additional cavity in dependence upon a frequency, for instance that of the local oscillator of a frequency converter, the simple storage of this frequency ensuring the tuning of the band-pass filter.
