A microwave oscillator having a hollow conductor, an oscillation generator which is mounted on a heatsink and projects into the hollow conductor, and a printed circuit board having electronic components for supplying direct voltage to the oscillation generator. The printed circuit board or a metallic coating on, in, or under this printed circuit board forms one wall of the hollow conductor, and the oscillator including its heatsink is located in the printed circuit board.

Microwave oscillator

The circuit device has a contact element, which electrically connects a wave guide (1) with a conductor strip (2). To avoid mechanical stresses due to thermal expansion the contact element is a pre-stressed prefabricated leaf spring having reproducible properties, which is bonded at one contacting area to the wave guide (1) or the conductor strip (2) by electrically conducting adhesive or glue, while a sliding contact is provided on the conductor strip (2) or the wave guide (1) at the other contacting area. The prefabricated leaf spring is preferably a MIGA leaf spring precisely made by UV depth lithography and multiplayer galvanic methods in a batch production process.
