DATA SHEET
HIGH POWER TRAVELING WAVE TUBE
FOR GROUND TERMINALS
LD7202 SERIES
14 GHz, 600 W CW, PPM FOCUSING, HIGH POWER GAIN
GENERAL DESCRIPTION
NEC LD7202 series of PPM-focused traveling wave tubes are designed for use as final amplifiers tube in the
earth-to-satellite communications transmitter.
These are capable of delivering an output power of 600W over the range of 12.75 to 14.5 GHz and provide a high
power gain of 52 dB at 600 W output power.
Furthermore, they are of rugged and reliable design offering long-life service.
The LD7202 is fully compatible with TH3591B.
FEATURES
™ High Power Gain
The power gain is typically 52 dB at 600 W level.
™ Simple Cooling System
The tubes are forced-air-cooled, so that the cooling systems are greatly simplified.
™ PPM Focusing
All 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 use in digital communication service.
For safe use of microwave tubes, refer to NEC document “Safety instructions to all personnel
handling electron tubes” (ET0048EJ∗V∗UM00)
