Summary:
This paper proposes a novel super-regenerative detector which is able to operate in multi-frequency bands. It operates in the same frequency as the fundamental oscillation and its harmonics of the oscillator in it, while conventional one operates in a single frequency band. An FET oscillator was used in the super-regenerative detection, whose fundamental frequency was 2.4 GHz. The detection of an on-off keying signal has been confirmed over a carrier frequency of 4.8 GHz which corresponds to the second harmonics as well as over a carrier frequency of 2.4 GHz (fundamental one). The dependency of the demodulated signal voltage on the input power is shown together with the time domain waveform.
