HIGH POWER CW KLYSTRONAMPLIFIER

FOR GROUND TERMINALS

LD4606A

30 GHz, 380 W CW, HIGH EFFICIENCY, HIGH POWER GAIN

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.
