Abstract
An amplifier including an electronic tube with an axial electron beam, provided with a cathode and at least two collectors, and at least two sources of DC voltage. Each collector is connected to a DC voltage source having a potential difference such that, the further the collector is from the cathode, the lower the potential difference between this collector and the cathode. The DC voltage sources are connected together at a common point situated at the collector whose potential difference with the cathode is the lower but not zero.
Claims17
An amplifier, comprising:
- an electron tube with an axial electron beam, provided with a cathode and at least two collectors;
- and
- at least two DC voltage sources, each collector being directly connected to a respective one of the at least two DC voltage sources having a potential difference therebetween such that, the further the collector is from the cathode, the lower the potential difference between this collector and the cathode,
- wherein the at least two DC voltage sources are connected together to a lower potential collector whose potential difference with the cathode is lower than a potential difference of all other collectors of the at least two collectors with the cathode, but the potential difference of the lower potential collector is not zero,
- wherein said amplifier is free of any DC voltage source connected to at least one of said at least two collectors and not connected to said lower potential collector.
