LD7260

· 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 performance across a broad power range and is ideally suited for multi-carrier transmission systems.
· 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 LD7260 is a PPM-focused traveling wave tube designed for use as final amplifiers in the earth-to- satellite communications transmitter.

This is capable of delivering an output power of 2.25 kW over the range of 5.85 to 6.425 GHZ and provides a power gain of 44 dB at rated output power. This is equipped with dual-stage depressed collector for enhancing overall efficiency.

Furthermore, this is of rugged and reliable design offering long-life service.
