Abstract

See full text

The present disclosure relates to an oscillator device (1, 1′, 1″, 1′″) comprising an active circuit device (2, 2′″), a circuit board (3) and a cavity resonator (4, 4′). The active circuit device (2, 2′″) comprises an amplifier unit (5), and the circuit board (3) comprises a first main side (6) and a second main side (7), where the active circuit device (2, 2′″) is mounted to the first main side (6). The cavity resonator (4, 4′) is positioned on the second main side (7). The oscillator device (1) further comprises at least one excitation via connection (8) that runs through the circuit board (3) and electrically connects the active circuit device (2, 2′″) to an excitation structure (9) inside the cavity resonator (4, 4′).
