HIGH POWER TRAVELING WAVE TUBE
FOR GROUND TERMINALS
LD7246A
14 GHz, 123 W CW, CONDUCTION COOLING, MINIMUM SIZE
GENERAL DESCRIPTION
NEC LD7246A is PPM-focused traveling wave tube designed for use as final amplifier in the earth-to-satellite
communications transmitter.
This is capable of delivering an output power of 130 W over the range of 13.75 to 14.5 GHz.
It provides a high power gain of 53 dB at 123 W output power.
Furthermore, this is of rugged and reliable design offering long-life services.
FEATURES
鈩?/div>
Light weight, Compact and Efficient
The tube has dual-depressed collectors and is designed to operate at high efficiency across wide power
output range. It features state-of the art techniques to optimize size and efficiency.
鈩?/div>
High Power Gain
The power gain is typically 53 dB at 123 W level.
鈩?/div>
Simple Cooling System
The tube is conduction-cooled, so that the cooling system is greatly simplified.
鈩?/div>
PPM Focusing
The tube is PPM (Periodic Permanent Magnet) -focused, eliminating entirely focusing power supplies and inter-
lock circuits.
鈩?/div>
Rugged Construction
The tube is designed to be rugged, therefore it is suitable for transportable systems.
鈩?/div>
Long Life and High Stability
The tube employs an advanced impregnated cathode with a low operating temperature for long life.
鈩?/div>
Microdischarge 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.
For safe use of microwave tubes, refer to NEC document 鈥淪afety instructions to all personnel
handling electron tubes鈥?(ET0048EJ鈭梀鈭桿M00)
