ABSTRACT:
An SHF converter with less change in local oscillation frequency due to change in ambient temperature. The SHF converter is at least equipped with a low noise amplifier 1; a local oscillator circuit 5 with a dielectric resonator 13; a frequency converter 3; and a power-supply stabilizing IC, characterized in that a temperature sensing section 7 for sensing the temperature of the surroundings is placed near a metal cavity 12 housing the dielectric resonator 13, a first power-supply stabilizing IC 6a is placed at such a position as to accomplish efficient transfer of its generated heat to the metal cavity 12, while a second power-supply stabilizing IC 6b is placed at such a position that transfer of its generated heat to the metal cavity 12 is impeded, and a switch control section 8 and a selector switch 9 are also provided to switch activation between the first and the second power-supply stabilizing ICs 6a and 6b in a manner concordant with the temperature sensing section 7.
