FEATURES
○ High Power Gain
The power gain is typically 45 dB at 600 W level and 54 dB at 700 W level.
○ Simple Cooling System
All the tubes are forced-air-cooled, so that the cooling systems are greatly simplified.
○ PPM Focusing
The tubes are PPM (Periodic Permanent Magnet) -focused, eliminating entirely the focusing power supplies and
interlock circuits.
○ Rugged Construction
The tubes are designed to be rugged, therefore they are suitable for transportable systems.
○ Long Life and High Stability
The tubes employ an advanced impregnated cathode with a low operating temperature for long life.
○ Microdischarge Free
The tubes are carefully designed to be free from microdischarge in the electron gun for long term operation, therefore they are suitable for digital communication service.
