Abstract
Stabilization on a desired frequency fo of a solid-state oscillator is obtained by means of an additional damping load 6 preventing oscillations outside a narrow band about this frequency. In order to prevent losses in said load, the load in question is cut out at frequency fo by a stop band filter 7 mounted in the transmission line to which is connected the oscillator, a negative resistance diode 4, arranged in series with the load and terminated on a reactive impedance. Realization may be carried out by way of microband technology for devices operating at 10 gigahertz with an output power of several watts.
Claims3
A microwave solid state oscillator comprising a negative resistance diode and associated with the latter means for producing radioelectric oscillations within the diode, means for coupling the diode to one end of a supply line, a cavity resonator coupled to said line and resonating on a frequency f.sub.o, a useful load and a damping load and a stop-band filter being connected to said line, said loads and filter being mounted in series on the line as viewed from said coupling, and said filter being equivalent to an infinite impedance at f.sub.o frequency and a very weak one outside a given band round f.sub.o.
