The present invention relates to an oscillator circuit (1, 1', 1", 1'", 1"") comprising at least one cavity (10, 16, 22, 33, 43) being arranged for supporting at least one predetermined resonance frequency for a signal that is input into said cavity (10, 16, 22, 33, 43). The oscillator circuit (1, 1', 1", 1'", 1"") is partly comprised in a package (2, 14, 19, 29, 40) with a number of electrically conducting connecting means (4, 15, 20, 30, 41 ) for electrically connecting the package (2, 14, 19, 29, 40) to a supporting planar structure (3, 3') having a first main side (5, 5'). The connecting means (4, 15, 20, 30, 41 ) form at least one circumference around a corresponding at least one surface structure (7, 7', 7", 7"' 7"") of a bottom side (8, 8', 8", 8'", 8"") of the package (2, 14, 19, 29, 40). The package (2, 14, 19, 29, 40) is arranged to be mounted on a metal ized structure (9, 9') on the first main side (5, 5') of the supporting planar structure (3, 3') such that an inner volume defined by one circumference of connecting means (4, 15, 20, 30, 41 ), the metalized structure (9, 9') on the first main side (5, 5') of the supporting planar structure (3, 3') and said surface structure (7, 7', 7", 7'", 7"") constitutes said cavity (10, 16, 22, 33, 43). |
