LD7213 - HIGH POWER TRAVELING WAVE TUBE

Datasheet Summary

Description

The NEC LD7213 and LD7213L are PPM-focused traveling wave-tubes designed for use as final amplifiers in the earth-to-satellite communications transmitter.

These are capable of delivering an output power of 300 W over the range of 14.0 to 14.5 GHz and 13.75 to 14.5 GHz.

Features

  • ™ High Power Gain The power gain is typically 58 dB at small signal level and 55 dB at 300 W level. ™ Simple Cooling System The tubes are conduction-cooled, so that the cooling systems are greatly simplified. ™ PPM (Periodic Permanent Magnet) 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. ™ Lon.
