Abstract (en)

[origin: WO2013000496A1] The present invention relates to an oscillator device (1, 1") comprising an amplifier unit (2) and a waveguide cavity resonator (3, 3', 3"). The waveguide cavity resonator (3', 3") comprises a first tuning element (4, 4") arranged for mounting in the waveguide cavity resonator (3, 3', 3"). The waveguide cavity resonator (3, 3', 3") has a first cavity Iength (a, a") between two opposing inner walls (7, 8; 37, 38) of the waveguide cavity resonator (3, 3', 3"), where a resonance frequency (fr) of the waveguide cavity resonator (3, 3', 3") is dependent on the first cavity iength (a, a"). The first tuning element (4, 4") is arranged for altering the first cavity length (a, a") between at feast two values (aeff1, aeff2; aeff1",aeff2'') such that the resonance frequency (fr) of the waveguide cavity resonator (3, 3', 3") is adjustable between at least two corresponding magnitudes.
