GENERAL DESCRIPTION
The NEC LD4606A is a five-cavity Klystron amplifier and
ideal for use in the earth-to-satellite communications trans-
mitter.
This is designed for operating at 380 W CW power lev-
els in the frequency range of 27.50 to 29.10 GHz. The in-
stantaneous 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 of-
fering long-life service.
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 sim-
plified.
4 Permanent Magnet
The klystron is permanent magnet focused, eliminat-
ing entirely the requirement for focusing power sup-
plied and interlock circuits.
5 Rugged Construction
The klystron is designed to be rugged.
