LD7714
Description
The NEC LD7714 is a PPM-focused traveling wave tube designed for use as final amplifier in the earth-tosatellite munications transmitter, LMDS (Local Multipoint distribution service) and other advanced munication systems. This is capable of delivering an output power of 40 W over the range of 27.5 to 30.0 GHz and provides a power gain of more than 40 dB at 40 W level.
Key Features
- It features state-of-the-art techniques to optimize size and efficiency
- 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 trancmission systems
- 6.0 – – 180 7.8 – 3.0 – 1.5 – – – Max
