LD7215規(guī)格書詳情

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.

They provide a high power gain of 46 dB at an output power of 3 kW, and flat gain variation of 2.5 dB by LD7215, 1.0 dB by LD7215C and LD7215D at small signal level in the full frequency range.

Furthermore, they are of rugged and reliable design offering long-life service.

Both LD7215 and LD7215D are fully compatible with TH3640.

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.

● 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.
