LD7262

· Lightweight, Compact and Efficient
The tube has dual-depressed collectors and designed to operate at high efficiency across the power output range. It features state-of-the-art techniques to optimize size and efficiency.
· Low Distortion
Distortion is a very important factor in multiplex digital signals transmission. NEC has developed techniques for the correction of non-linear distortion and phase generated in a TWT. As a result, the TWT has an opti-mum pertormance across a broad power range and is ideally suited for multi-carrier transmission systems.
· Simple Cooling System
The tube is conduction cooled, so that the cooling system is simplified.
· Rugged Construction
The power gain 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.
· Micro-discharge 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 LD7262 series of PPM focused traveling wave tubes are designed for final amplifier in the earth-to- satellite communication's transmitter.

These are capable of delivering an output power of 750 W over the range of 5.85 to 6.45 GHZ and an output power of 700 W over the range of 5.85 to 7.1 GHZ With a power gain of more than 45 dB at any power level.

Furthermore, LD7262 are rugged and reliable design offering long life services.
