LD7267 - HIGH POWER TRAVELING WAVE TUBE

Datasheet Summary

Description

The NEC LD7267 series of PPM-focused traveling wave tubes are designed for use as final amplifiers in the earth-to-satellite communications transmitter, LMDS (Local Multipoint Distribution Service) and other advanced communication systems.

Features

  • ™ High Power Gain The power gain is typically 50 dB at 100 W level. ™ Simple Cooling System The tubes are conduction-cooled, so that the cooling systems are greatly simplified. ™ PPM Focusing The tubes are PPM (Periodic Permanent Magnet) -focused, eliminating entirely the focusing power supplies and interlock circuits. ™ Rugged Construction The tubes are designed to be rugged, therefore they are suitable for transportable systems. ™ Long Life and High Stability The tubes employ an advanced impre.
