HIGH POWER TRAVELING WAVE TUBE
FOR GROUND TERMINALS
LD7215W
For safe use of microwave tubes, refer to NEC document “Safety instructions to all personnel
handling electron tubes” (ET0048EJ
V
UM00)
GENERAL DESCRIPTION
NEC LD7215W is a 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 3 kW over the range of 5.85 to 6.65 GHz.
It provides a high power gain of 42 dB at a rated output power.
Furthermore, this is of rugged and reliable design offering long-life service.
FEATURES
High Power Gain
The power gain is typically 42 dB minimum at 3 kW level.
Simple Cooling System
The tube is forced-air-cooled, so that the cooling systems are simplified.
PPM Focusing
The tube is PPM (Periodic Permanent Magnet) -focused, eliminating entirely the focusing power supplies and
interlock circuits.
Rugged Construction
The tube is designed to be rugged, therefore it is suitable for transportable systems.
Long Life and High Stability
The tube employs an advanced impregnated cathode with a low operating temperature for long life.
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.
