Abstract
An oscillator comprising an oscillator body having a waveguide and a substantially cylindrical bore intersecting the waveguide, and a package comprising a heat sink having a substantially cylindrical portion and an oscillatory semiconductor device supported at one end of the heat sink. The diameter of the cylindrical portion of the heat sink in relation to the diameter of the bore is such that the heat sink is supported in the bore by one of an interference fit and a tight sliding fit, with the semiconductor device being located in the waveguide. The tight sliding fit or interference fit includes a layer of soft deformable material.
