Abstract

PURPOSE:To enable receive at all times at optimum reception sensitivity, by providing the frequency controlling means which can oscillate the quenching frequency corresponding to the optimum sensitivity of the quenching oscillating circuit of front end of superregenerative system. CONSTITUTION:After the input signal of high frequency from the antenna 1 is demodulated at the quenching oscillation circuit 8 and the oscillation waveform is shaped at the wave shaping circuit 24, it is input to the frequency proportion output circuit 22. The resonance frequency of the resonance circuit consisting of the capacitor CR and variable coil LR of the circuit 22 is adjusted to the optimum frequency to the reception sensitivity of quenching frequency, and the rectified output is fed to the base voltage driving circuit 23 from the diode D, the base voltage of the transistor T2 of the quenching oscillation circuit 8 is controlled according to the output of the output circuit proportional to frequency 22, and the output voltage of the circuit 22 is driven so that it is maximum. Thus, optimum reception can be made at all times independently of the change in the external conditions such as temperature and voltage, without making reception unable tentatively.
