Definitions

  • FIG. 1 there is shown an electron tube oscillator I for the generation of high frequency oscillations.
  • the grid and anode electrodes of tube I are coupled to opposite terminals of a tuned oscillatory circuit comprising an inductor 2 and a parallel connected variable capacitor 3, while the cathode K is connected to an intermediate point on the inductor 2.
  • a suitable grid-leak and condenser combination 4 supplies bias to the grid of the tube I, while a source of anode potential +13 supplies a positive polarizing potential to the anode of tube I through a radio frequency choke coil 5.
  • a compensating tube 6 whose grid-cathode or input capacity is disposed in parallel to a portion of the oscillatory circuit 2, 3; more specifically, across the low potential part of inductor 2 and in parallel relation to the anode-cathode capacity of the oscillator tube I.
  • the anode of electron tube 6 is connected to the positive terminal of the source of anode supply +B, as shown, both anodes being by-passed to ground from a radio frequency standpoint.
  • the negative bias on the grid of compensating tube 6 is adjusted by means of the cathode tap I on potentiometer 8.
