TRAVELING WAVE TUBE AMPLIFIER

FOR GROUND TERMINALS

LD79U12K

14 GHz, 123 W CW, LIGHT WEIGHT, COMPACT, EFFICIENT

GENERAL DESCRIPTION

NEC TWTA (Traveling Wave Tube Am plifier) 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 enorm ous experience on a num ber of TWTs used in satellite ground term inals and ter-

restrial m icrowave links.

The very sm all and light weight Electric Power Conditioners (EPC) designed with sophisticated and experienced

circuit technology ensures higher reliability, reduced m aintenance costs and im proved technical perform -

a n ce .

The LD79U12K is m ost suitable for a power am plifier in digital com m unication system s.

FEATURES

™ Light weight, Com pact, 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 optim ize size and efficiency and the com bination results

in a unit significantly sm aller and with less power consum ption than a com parable solid state am plifier.

™ 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 optim um perform ance across a broad power range and is ideally suited for m ulti-

carrier transm ission system s.

™ Long Life

The TWT is designed to have a lifetim e of 50,000 hours or m ore, which in actual usage.

™ Ideal for Digital System s

A m ini-arcing in the electron gun have been elim inated in the TWT used in the TWTA.

™ Wide range of prim ary voltage

For safe use of m icrow ave tubes, refer to NEC docum ent “Safety instructions to all personnel

handling electron tubes” (ET0048EJ V UM00)

The inform ation in this docum ent is subject to change w ithout notice.
