TRAVELING WAVE TUBE AMPLIFIER
FOR GROUND TERMINALS
LD79U12K
14 GHz, 123 W CW, LIGHT WEIGHT, COMPACT, EFFICIENT
GENERAL DESCRIPTION
NEC TWTA (Traveling Wave Tube Amplifier) LD79U12K delivers an output power of 123 W over the range of
13.75 to 14.5 GHz with a gain of 50 dB.
The Traveling Wave Tube (TWT : LD7246A) in the LD79U12K has been designed and developed upon the NEC's
advanced technology and enormous experience on a number of TWTs used in satellite ground terminals and ter-
restrial microwave links.
The very small and light weight Electric Power Conditioners (EPC) designed with sophisticated and experienced
circuit technology ensures higher reliability, reduced maintenance costs and improved technical perform-
ance.
The LD79U12K is most suitable for a power amplifier in digital communication systems.
FEATURES
鈩?/div>
Light weight, Compact, and Efficient
The TWT has a dual-depressed collector and is designed to operate at high efficiency across the power output
range. The EPC features state-of-the-art techniques to optimize size and efficiency and the combination results
in a unit significantly smaller and with less power consumption than a comparable solid state amplifier.
鈩?/div>
Low Distortion
NEC has developed techniques for the correction of non-linear distortion of gain and phase generated in a TWT.
As a result, the TWTA has optimum performance across a broad power range and is ideally suited for multi-
carrier transmission systems.
鈩?/div>
Long Life
The TWT is designed to have a lifetime of 50,000 hours or more, which in actual usage.
鈩?/div>
Ideal for Digital Systems
A mini-arcing in the electron gun have been eliminated in the TWT used in the TWTA.
