Description



Features:

1 High Efficiency The DC to RF conversion efficiency is typically 23 % by incorporating a 39 % depressed collector.
2 High Power Gain The power gain is typically 40 dB at the 380 W level, so the driving power is less than 50 mW.
3 Simple Cooling System The klystron is all forced air cooled with only one blower, so that the cooling systems are greatly simplified.
4 Permanent Magnet The klystron is permanent magnet focused, eliminating entirely the requirement for focusing power supplied and interlock circuits.
5 Rugged Construction The klystron is designed to be rugged.

Description

The NEC LD4606A is a five-cavity Klystron amplifier and ideal for use in the earth-to-satellite communications transmitter.

The LD4606A is designed for operating at 380 W CW power levels in the frequency range of 27.50 to 29.10 GHz. The instantaneous bandwidth of minus one-decibel is at least 70 MHz over the entire 1.6 GHz range.

The tube is forced-air-cooled at the 380 W operation. Furthermore, this is of rugged and reliable design offering long-life service.
