ABSTRACT:
The microwave oscillator is formed by a free oscillator 1 coupled with two surface or volume acoustic wave delay lines 9 and 10 connected in series or in parallel and operating by reflection. The first line imposes a delay 2.tau..sub.1, corresponding to one reciprocation, which is a multiple of the delay 2.tau..sub.2 imposed by the second line, and a=.tau.1/.tau.2 is preferably equal to 2 or 3. Application to oscillators operating at ultra-high frequencies, particularly in the L-band.
