DATA SHEET
HIGH POWER TRAVELING WAVE TUBE
FOR GROUND TERMINALS
LD7217 SERIES
6 GHz, 600 W/700 W CW, PPM FOCUSING,
HIGH POWER GAIN
GENERAL DESCRIPTION
NEC LD7217 series of PPM-focused traveling wave tubes are designed for use as final amplifiers in the earth-to-
satellite communications transmitter.
LD7217S and LD7217 are capable of delivering an output power of 600 W and 700 W over the range of 5.85 to
6.425 GHz and provide a high gain of 45 / 54 dB at 600 / 700 W level . In addition, LD7217W is capable of delivering
an output power of 700 W with a gain of 54 dB over the range of 5.85 to 6.65 GHz. The LD7217 series provide a flat
gain variation of 1.5dB (LD7217S) ,1.0dB (LD7217) and 1.8dB (LD7217W) at any power level.
Furthermore, these are of rugged and reliable design offering long-life service.
LD7217S is fully compatible with VTC6361B3, and LD7217 is also fully compatible with VTC6361B4.
FEATURES
™ High Power Gain
The power gain is typically 45 dB at 600 W level and 54 dB at 700 W level.
™ Simple Cooling System
All the tubes are forced-air-cooled, so that the cooling systems are greatly simplified.
™ PPM 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 an advanced impregnated cathode 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.
For safe use of microwave tubes, refer to NEC document “Safety instructions to all personnel
handling electron tubes” (ET0048EJ∗V∗UM00)
