General Description

The NEC LD7235 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.

Three models of the LD7235 series are capable of delivering an output power of 150 W over the range of 26.5 GHz to 31.1 GHz and provide a high power gain of 50 dB at 150 W output power.

These are equipped with dual-stage depressed collector for enhancing overall efficiency and a single collector.

Overview

DATA S H E E T HIGH POWER TRAVELING WAVE TUBE FOR COMMUNICATIONS LD7235 SERIES 30 GHz, 150 W CW, CONDUCTION COOLING, HIGH POWER.

Key Features

  • ™ High Power Gain The power gain is typically 50 dB at 150 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.
