HIGH POWER TRAVELING WAVE TUBE
FOR GROUND TERMINALS
LD7213, LD7213L
For safe use of microwave tubes, refer to NEC document “Safety instructions to all personnel
handling electron tubes” (ET0048EJ
V
UM00)
GENERAL DESCRIPTION
The NEC LD7213 and LD7213L are PPM-focused traveling wave-tubes designed for use as final amplifiers in the
earth-to-satellite communications transmitter.
These are capable of delivering an output power of 300 W over the range of 14.0 to 14.5 GHz and 13.75 to 14.5
GHz.
They provide a high power gain of 55 dB at 300 W output, and flat gain variation of 1.5 dB at any power level.
LD7213 is fully compatible with TH3759K.
FEATURES
High Power Gain
The power gain is typically 58 dB at small signal level and 55 dB at 300 W level.
Simple Cooling System
The tubes are conduction-cooled, so that the cooling systems are greatly simplified.
PPM (Periodic Permanent Magnet) Focusing
The tubes are PPM (Periodic Permanent Magnet) -focused, eliminating entirely the focusing power supplies and
interlock circuits.
Rugged Construction
The tubes are designed to be rugged, therefore they are suitable for transportable systems.
Long Life and High Stability
The tubes employ advanced impregnated cathodes with a low operating temperature for long life.
Microdischarge Free
The tubes are carefully designed to be free from microdischarge in the electron gun for long term operation,
therefore they are suitable for digital communication service.
