Vf 2.5 Volts / If 6 Ampere |
| Description |
High-power voltage-tunable CW magnetron (VTM). 4800 to 5300MHz, 75W minimum output power, 1.4 dB power variation over the tuning range, 2.0MHz/V tuning sensitivity.
Integral output isolator.
The VTM, Voltage Tuned Magnetron, covers a wide frequency range. Its operation is quite different from that of resonant cavity types, where bunching is easily accomplished due to the high Q of the cavities. To have electron bunching, the VTM must operate with an electron current lower than the space-charge limited one: this is accomplished using a cold cathode in addition to an injection system with a filamentary cathode. The operating principle is described in the application note given for the ZM-6222 type.
Theory of operation.
