Abstract
A multibeam-inductive-output-tube amplifier comprises an output cavity and a plurality of electron guns each intended to emit an electron beam through the output cavity, each electron gun comprising a cathode intended to emit the electron beam and a gate allowing the density of the electron beam to be modulated. The amplifier comprises, associated with each gun, a DC voltage supply, each of the supplies connected to the gate of the corresponding electron gun so as to bias the gate. The voltage of at least one of the supplies is adjustable so as to balance the density of the various electron beams.
Claims7
An amplifier comprising:
- a multibeam inductive output tube comprising an output cavity:
- and
- a plurality of electron guns that are each intended to emit an electron beam through the output cavity, each electron gun comprising:
- a cathode that is intended to emit the electron beam, and
- a gate in a path of the electron beam allowing the density of the electron beam to be modulated:
- and
- a DC voltage supply associated with each gun, each DC voltage supply being connected to the gate of the corresponding electron gun so as to bias the gate, the voltage of at least one DC voltage supply being adjustable so as to balance the density of the various electron beams.
