LD7246A Features
· Light weight, Compact and Efficient
The tube has dual-depressed collectors and is designed to operate at high efficiency across wide power output range. It features state-of the art techniques to optimize size and efficiency.
· High Power Gain
The power gain is typically 53 dB at 123 W level.
· Simple Cooling System
The tube is conduction-cooled, so that the cooling system is greatly simplified.
· PPM Focusing
The tube is PPM (Periodic Permanent Magnet) -focused, eliminating entirely focusing power supplies and inter-lock circuits.
· Rugged Construction
The tube is designed to be rugged, therefore it is suitable for transportable systems.
· Long Life and High Stability
The tube employs an advanced impregnated cathode with a low operating temperature for long life.
· Microdischarge Free
The tube is carefully designed to be free from microdischarge in the electron gun for long term operation,therefore it is suitable for digital communication service.
