HIGH POWER TRAVELING WAVE TUBE
FOR COMMUNICATIONS
LD7263
14 GHz, 750 W CW, CONDUCTION COOLING, HIGH POWER GAIN
GENERAL DESCRIPTION
The NEC LD7263 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 750 W over the range of 1 3.75 to 14.5 GHZ and provides a
power gain of more than 47 dB at 750 W Ievel.
Furthermore, this is of rugged and reliable design offering long-Iife service.
FEATURES
™ 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.
™ 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.
For safe use of microwave tubes, refer to NEC document “Safety instructions to all personnel
handling electron tubes” (ET0048EJ∗V∗UM00)
