CV6162 travelling wave tube
 |
This TWT measurs 438x35mm overall and 12mm across the stem. It has 3 leads, red, yellow and blue. |
This TWT carries the markings GPO 1345, W7/4G (the commercial equivalent) 8249, and has KX34 scratched onto the metal base.
| Heater voltage | 6.3V |
| Frequency range | 3.6 to 4.2GHz |
| Gain | 39dB nominal at 7W output |
| Noise factor at working output | 27dB |
| Typical operating conditions |
| Collector voltage | 2kV |
| Helix voltage | 3kV |
| Cathode current | 40mA |
This example came with a test certificate as follows:
| Frequency | 3.6GHz | 3.8GHz | 4.2GHz |
| Helix voltage | 2980V | 2955V | 2920V |
| Gain (at 7W) | 39.7dB | 38.6dB | 37.8dB |
| Max power output | 9.9W | 9.7W | 9.7W |
The above measurements were with a heater voltage of 6.3V, grid 2 voltage of 1890V, collector voltage of 2kV and 40mA cathode current.
