ABSTRACT:
A transmission line microwave oscillator having two degrees of freedom wherein the real portion, R.sub.in, of the input impedence seen by the active device is adjustable by changing the coupling coefficient between and active device and a resonator and where the external quality, Q.sub.EXT, of the oscillator is adjustable by changing the coupling between the resonator and an output transmission line.
