Product Details

Description



Features:

· High Power Gain
The power gain is typically 52 dB at 600 W level.
· Simple Cooling System
The tubes are forced-air-cooled, so that the cooling systems are greatly simplified.
· PPM Focusing
All 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 use in digital communication service.
