ABSTRACT:
The present invention relates to a microwave oscillator to be applied to radiosonde. The microwave oscillator in accordance with the present invention is constructed on a plane base plate of dielectric material (insulation material) on whose both sides conductor sheets are provided. The resonance circuit, which is the most important part of the microwave oscillator, is mounted fixedly on the one side of the base plate and electrically connected to the conductor sheet provided on the other side of the base plate. The element for determining the resonance frequency of this resonance circuit assumes a three dimensional form, whereby two bent conductor plates are combined into a case shaped body, whose one side is constructionally and electrically connected to the conductor sheet provided on the one side of the base plate.
The transistor, which is an active element of the resonance circuit, is constructionally and electrically connected to a part of the case shaped metal body.
The circuit elements for forming the oscillator circuit, such as resistors, the condensers and the transistor and so on are mounted on the other side of the base plate.
