Abstract

1,046,911. Automatic frequency control systems. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Jan. 15, 1965 [Jan. 23, 1964], No. 1980/65. Heading H3A. A cavity resonator oscillator is tuned by an inner conductor 3 in series with a tuning capacitor 4 and is frequency controlled by a further conductor 5, parallel with and inductively coupled with the conductor 3, with one end connected to the resonator casing, and the other end connected in series through an inductor 7 and a voltage variable capacity diode 8 to a control voltage. This other end of conductor 5 and the input end of diode circuit 7, 8 are also connected to the casing by a capacitor 6 and by lead-through capacitor 10 respectively. The coupling inductor 5 and capacitor 6 should be tuned above the highest oscillator frequency, and the diode 8 and inductor 7 tuned below the lowest frequency, for constant oscillator frequency change produced by the control voltage over the whole tuning range. The inductor 7 may be formed from the diode wire lead. The oscillator may form part of a self-oscillating mixing stage.
