Title: Superregenerative wave-signal receiver
IPC: H03D11/02
Filed: 1947-07-21
Abstract: 638,204. Valve super-regenerative receivers. HAZELTINE CORPORATION. July 21, 1947, No. 19542. Convention date, Aug. 7, 1946. [Classes 40 (v) and 40 (vi)] A super-regenerative amplifier for F.M. or A.M. signals operates at an intermediate frequency produced by applying the received signals and a local oscillation to the super-regenerator. Fig. 4 shows a receiver for amplitude modulation comprising a signal frequency input circuit 23 a linear mode super-regenerative amplifier valve 10, a detector 29 and a combined local oscillator and quench generator 0. The anode circuit of valve 10 includes an I.F. tuned circuit 13, 14, 15 connected to cause the valve to oscillate. Inductor 19 resonates with capacitor 15 at the signal frequency to ensure the application of the full input voltage between grid and cathode. The required local oscillation frequency and quench voltage are generated in a cathode feedback blocking oscillator 0, the local oscillation being applied to the grid of the amplifier through capacitor 48 and the quench voltage which is of saw-tooth form being applied to the same grid from the cathode resistor 42. Resistors 46 and 47 bias valve 10 to cut-off. The local oscillation and quench voltage may be generated separately and either both applied in series with the anode circuit of the amplifier (Fig. 1, not shown), or the quench voltage may 100 per cent modulate the local oscillator (Fig. 3, not shown). In both cases the H.T. D.C. supply to the amplifier may be omitted. Fig. 5 shows an F.M. receiver comprising two logarithmic mode superregenerative amplifiers 10, 10<1>a in circuit arrangements similar to Fig. 4 to which the signal is applied in phase and from which the output is derived in push-pull. The I.F. oscillatory circuits 13, 14, 15 and 13a, 14a, 15a, which in this arrangement are connected to the screen grids are tuned one above and one below the intermediate frequency and by operating the super-regenerators in the logarithmic mode the modulation frequency is produced in the anode circuits. The quench voltage produced in blocking oscillator 0 is applied through a resistance-capacitance network 56, 57 to produce a more rounded waveform. The output characteristic corresponds to a probability function as disclosed in Specfication 626,154.
