Patent ID: 8427248

Claim:
A stabilization network comprising: a resistance connected between an output terminal and a drain terminal electrode of an active element which generates a negative resistance at an oscillation frequency of a high frequency negative resistance oscillation of Gunn oscillation and a value of the resistance is equal to an absolute value of the negative resistance; and a tank circuit which is composed of an inductance and a capacitance which are connected in parallel with the resistance and synchronize with the oscillating frequency of the high frequency negative resistance oscillation, wherein the capacitance is placed on an upper part or a lower part of the resistance, and the capacitance has an inter-digital capacitance structure composed of a first metal layer and a second metal layer placed adjacent to the first metal layer, wherein the oscillation frequency is tuned with a resonance frequency of the tank circuit, so that the negative resistance of the active element is canceled by using the value of the resistance at the oscillation frequency, a source inductance is connected between a source of the active element being only a single active element and grounding electric potential.
