Definitions

  • a source of radio frequency I9 is coupled bythe tuned circuit 20, 2
  • the effect of the radio frequency drive is to give an electron beam modulated at radio frequency.
  • the target plate I1 is coupled by means of tuned circuit 22, 23 to the final anode it, which is at cathode potential for the carrier frequency. During such time as the beam strikes the target plate ll, a radio frequency at the same frequency as supplied by the input 19 is present in the circuit 22, 23.
  • said output circuit comprises a first circuit connected to one of said target portions, a second circuit connected to the other of said target portions, and a third circuit coupled to said first and second circuits, the coupling between said flrst and third circuits being different from the coupling between said second and third circuits.
