· High Power Gain
The power gain is typically 40 dB at 250 W level.
· Simple Cooling System
All the tubes are forced-air-cooled, so that the cooling systems are greatly simplified.
· PPM Focusing
The tube is PPM (Periodic Permanent Magnet) -focused, eliminating entirely the focusing power supplies and interlock 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.
The NEC LD7261 is a PPM-focused traveling wave tube designed for use as final amplifier in the earth-to-satellite communications transmitter.
This is capable of delivering an output power of 250 W over the range of 18.0 to 21.7 GHz and provides a power gain of more than 40 dB at 250 W.
Furthermore, LD7261 is rugged and reliable design offers long-life service.
