Abstract
A solid-state MIC oscillator in the form of a planar transmission circuit has a band rejection filter as a load circuit of an oscillation device. The band rejection filter is a resonator coupled to a transmission line which connects the oscillation device with an oscillator load. The load impedance of the oscillation device is adjusted to the oscillating condition by the position of the resonator. A simple capacitive susceptance stub is connected to the transmission line near the coupling point of the resonator. Variation of the oscillator frequency characteristics versus temperature caused by variation of the oscillator load is improved in an excellent manner due to the provision of the simple capacitive susceptance stub.
