LD4606A中文资料瑞萨数据手册PDF规格书

GENERAL DESCRIPTION

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

This 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.

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.
