Patent ID: 7167057

Claim:
A microwave oscillator comprising: a heatsink; a hollow conductor; an oscillation generator mounted on the heatsink and projecting into the hollow conductor; a printed circuit board having electronic components for supplying direct voltage to the oscillation generator, and a stripline situated on the printed circuit board, the stripline being coupled to a microwave field within the hollow conductor and being guided out of the hollow conductor as a microwave output, wherein one of (a) the printed circuit board and (b) a metal layer situated one of (1) on, (2) in, and (3) under the printed circuit board forms a wall of the hollow conductor, and the oscillation generator and the heatsink are situated in the printed circuit board, wherein the hollow conductor is expanded to form a resonator chamber in an area of the oscillation generator, and wherein the hollow conductor is impervious to a fundamental wave in the resonator chamber, and a distance between the stripline and the resonator chamber is greater than a decay distance of the fundamental wave.
