ABSTRACT:
A high-frequency signal generator has upper and lower conductive plates parallel to each other, at least one dielectric rod held between the upper and lower conductive plates, a metal mount sandwiched between the upper and lower conductive plates, a oscillating element mounted on a side of the mount for generating a high-frequency signal, a printed-circuit board mounted on the side of the mount and including a bias supply circuit disposed on a surface thereof for supplying a bias voltage to the oscillating element to enable the oscillating element to generate a high-frequency signal, and a positional displacement preventing structure on at least one of the upper and lower conductive plates for preventing the mount from being positionally displaced with respect to the dielectric rod. The positional displacement preventing structure may comprise a groove defined in at least one of the upper and lower conductive plates, the mount being partly fitted in the groove.
