A new method of producing millimeter - wave oscillator/mixers and associated antenna horns has been developed. This uses the technique of metal coating of a dielectric body, and hence avoids the expensive and difficult machining of conventional metal cavities. A sensitive self-oscillating mixer has been tested in this structure and shown to be free from the unstable operation associated with surface radiation of unshielded dielectric waveguide. Low cr dielectric was used, thus facilitating ease of matching in contrast with the high rnecessary with unshielded guide.
