LD79U12K

· 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.
· 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.
· Long Life
The TWT is designed to have a lifetime of 50,000 hours or more, which in actual usage.
· Ideal for Digital Systems
A mini-arcing in the electron gun have been eliminated in the TWT used in the TWTA.
· Wide range of primary voltage

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  up on the NEC's dvanced 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.
