LD7237 - HIGH POWER TRAVELING WAVE TUBE

Datasheet Summary

Description

NEC LD7237 is 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 400 W over the range of 17.3 to 18.1 GHz and provides a high power gain of 53 dB at 400 W output power.

Features

  • ™ High Power Gain The power gain is typically 53dB at 400 W level. ™ Simple Cooling System The tube is 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 the transportable systems. ™ Long Life and High Stability The tube employs an advanced impregnated.
