LD7215C - HIGH POWER TRAVELING WAVE TUBE

General Description

The NEC LD7215, LD7215C and LD7215D are PPM-focused traveling wave tubes designed for use as the final amplifiers in the earth-to-satellite communications transmitter.

These are capable of delivering an output of 3 kW over the range of 5.85 to 6.425 GHz.

Key Features

  • ™ High Power Gain The power gain is typically 52 dB at small signal level and 46 dB at 3 kW Ievel. ™ Simple Cooling System All the tubes are forced-air-cooled, so that the cooling system is greatly simplified. ™ PPM Focusing The tubes are PPM (Periodic Permanent Magnet) focused, and eliminate entirely the requirement for focusing power supplies and interlock circuits. ™ Long Life and High Stability The tubes employ advanced impregnated cathode with a low operating temperature for long life. ™ Mi.
