Overview
DATA S H E E T HIGH POWER TRAVELING WAVE TUBE FOR COMMUNICATIONS LD7262 SERIES 6 GHz, 750 W CW, CONDUCTION COOLING, HIGH POWER GAIN GENERAL DESCRIPTION The NEC LD7262 series of PPM focused traveling wave tubes are designed for final amplifier in the earth-tosatellite 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, these are rugged and reliable design offering long life services.
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 optimum 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.
For safe use of microwave tubes, refer to NEC document “Safety instructions to all personnel handling electron tubes” (ET0048EJ∗V∗UM00) The information in this document is subject to change without notice.
