Abstract
A microwave/millimeter-wave integrated circuit (IC) realizes stable oscillation by reducing time-based variation of a load impedance. This IC connects an oscillator to an input terminal of a Lange coupler and connects to the isolation port of the Lange coupler a terminating resistor having a resistance equal to the load impedance connected to the output terminals of the Lange coupler. This connection stabilizes load impedance to the oscillator, and reduces variation in the oscillation frequency as a result of changes in load impedance.
