前言在雷达中使用高稳定、相干的射频高功率放大器,应当降低被放大射频波形的相位失真。要达到所需的相位稳定度,就必须考虑所用灯丝电源的影响。本文叙述三种精稳的灯丝电源,供高性能雷达的高功率线型电子束射频放大管应用。它们是:直流灯丝电源、间断式非同步交流灯丝电源,和同步的交流灯丝电源。同步的交流灯丝电源有下述好处: 1.它对高压脉冲变压器的影响,比直 Preface The use of high-stability, coherent RF high-power amplifiers in radars should reduce the phase distortion of the amplified RF waveform. To achieve the required phase stability, the influence of the filament power used must be taken into account. This article describes three precise filament power supplies for high-power radar high-power line-beam RF amplifier applications. They are: DC filament power, discontinuous AC filament power, and AC power filament. Synchronous AC filament power supply has the following benefits: 1. Its impact on high-voltage pulse transformers, than the straight
