| 摘要 |
The invention relates to an amplifier comprising an axial electron beam electronic tube provided with a cathode (16) and at least to collectors (14a, 14b) and at least two continuous voltage sources. Each collector (14a, 14b) is connected to the continuous voltage source whose potential difference is directly proportional to the distance between the collector and the cathode. Said invention is characterised in that the voltage sources are interconnected at a common point (32) which is arranged near the collector (14b) whose potential difference is lower than the potential difference of the other collector but is higher than zero. |
