A frequency converter including a first pair of transistors with an interconnection between their emitters for receiving a unidirectional current with signal variations to be converted, at least one of their collectors arranged to supply converted signal currents. A second pair of transistors with an interconnection between their emitter electrodes connected by resistor to reference potential is connected to regenerate oscillations in a tank circuit. One of these transistors has its collector connected to the tank circuit; the other has its base connected to receive scaled-down oscillations from the tank circuit and has its collector provided with a resistive load to develop switching signal to be applied between the base electrodes of the first pair of transistors. Appropriate scaling of the resistive load to the emitter resistor shared by second pair of transistors results in maximum conversion efficiency.
