GENERAL DESCRIPTION
The NEC LD7267 series of PPM-focused traveling wave tubes are designed for use as final amplifiers in the earth-to-satellite communications transmitter, LMDS (Local Multipoint Distribution Service) and other advanced communication systems.
Three models of the LD7267 series are capable of delivering an output power of 100 W over the range of 26.5 GHz to 31.1 GHz and provide a high power gain of 50 dB at 100 W output power. These are equipped with dualstage depressed collector for enhancing overall efficiency and a single collector.
Furthermore, they are of rugged and reliable design offering long-life service.
FEATURES
○ High Power Gain
The power gain is typically 50 dB at 100 W level.
○ Simple Cooling System
The tubes are conduction-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.
