Abstract
A temperature-stabilized MIC solid state oscillator in the form of a planar transmission circuit has two strip line resonators respectively having chip capacitors inserted serially in the middle of the strip lines. Both of the chip capacitors have linear capacitance temperature characteristics. One strip line resonator operates as a band rejection filter and as a load circuit of an oscillating device. The other strip line resonator operates as a serial resonator to ground a port of the oscillating device that should be grounded. The oscillating frequency characteristics versus temperature are compensated in an excellent manner due to the provision of the two strip line resonators.
