LD7261 - HIGH POWER TRAVELING WAVE TUBE

Datasheet Summary

Description

The NEC LD7261 is a PPM-focused traveling wave tube designed for use as final amplifier in the earth-tosatellite communications transmitter.

This is capable of delivering an output power of 250 W over the range of 18.0 to 21.7 GHz and provides a power gain of more than 40 dB at 250 W.

Features

  • ™ High Power Gain The power gain is typically 40 dB at 250 W level. ™ Simple Cooling System All the tubes are 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 transportable systems. ™ Long Life and High Stability The tube employs an advanced impregna.
