NRD guide Gunn oscillator

摘要

A NRD guide Gunn oscillator obtained by disposing two parallel plates of metal at a distance that is not more than half a free-space wavelength of an used frequency and combining a NRD guide circuit sandwiching a dielectric strip line between the parallel plates and a Gunn diode, wherein the NRD guide Gunn oscillator comprises a plate substrate of insulating or semi-insulating material on which surface there are formed a signal electrode connected to a signal line and a ground electrode insulated with respect to the signal electrode, a Gunn diode being formed with an anode electrode and a cathode electrode on a same plane wherein one of the electrodes is connected to the signal electrode of the plate substrate and the other one is connected to the ground electrode, and a heat sink for supporting a rear surface of the plate substrate with respect to the one of the parallel plates, and wherein a tip of the signal line of the plate substrate is electromagnetically combined to the dielectric strip line. <IMAGE>
