  • Tunable microwave coupler with mechanically adjustable conductors
    Patent number: 4928077
    Abstract: Disclosed is a three-plate type coupler providing for the partial tapping, by means of plungers, of a microwave energy which is propagated in a guide. The coupler has mechanical means to vary the height of the central conductor of the three-plate structure at the level at which the plungers are fixed, thus causing a variation in the penetration of the plungers in the waveguide and, consequently, a variation in the coupling.
