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.
