LD7272规格书详情

GENERAL DESCRIPTION

The NEC LD7272 series of PPM focused traveling wave tubes are designed for final amplifier in the earth-tosatellite communications transmitter.

These are capable of delivering an output power of 400 W over the range of 5.85 to 6.45 GHZ and an output power of 400 W over the range of 5.85 to 7.1 GHZ with a power gain of more than 49 dB at any power level.

Furthermore, these are rugged and reliable design offering long life services.

FEATURES

● Lightweight, Compact and Efficient

The tube has dual-depressed collectors and designed to operate at high efficiency across the power output range. It features state-of-the-art techniques to optimize size and efficiency.

● Low Distortion

Distortion is a very important factor in multiplex digital signals transmission. NEC has developed techniques for the correction of non-linear distortion and phase generated in a TWT. As a result, the TWT has an optimum performance across a broad power range and is ideally suited for multi-carrier transmission systems.

● Simple Cooling System

The tube is conduction cooled, so that the cooling system is simplified.

● Rugged Construction

The power gain is designed to be rugged, therefore it is suitable for transportable systems.

● Long Life and High Stability

The tube employs an advanced impregnated cathode with a low operating temperature for long life.

● Micro-discharge Free

The tube is carefully designed to be free from microdischarge in the electron gun for long term operation, therefore it is suitable for digital communication service.
