微波频段的静磁波器件,目前正沿着两个方向迅速地发展着。一个方向是:研制可以直接在微波频段进行模拟信号处理的器件。在不久的将来,在微波频率上进行信号处理的重要作用,完全可以和当前已发展成熟的中频信号处理器件——声表面波器件在系统中的地位相比拟。最著名的器件有:信噪比增强器,其中心频率f。可高于4千兆赫。目前西屋电气公司已有样品报导,其性能指标为:在15分贝毫瓦电平下,有10分贝的增强,其带宽为800兆赫。可编程序4抽头延迟线,西屋电气公司报导的样品技术指标
The magnetostatic wave device in the microwave band is rapidly developing in two directions at present. One direction is to develop a device that can process analog signals directly in the microwave band. In the near future, the important role of signal processing on the microwave frequency can be compared with that of the currently mature IF signal processing device-surface acoustic wave device in the system. The most famous devices are: signal to noise ratio enhancer, the center frequency f. May be higher than 4 gigahertz. Current Westinghouse samples have been reported with performance specifications of 10 dB at 15 dB milliwatts and a bandwidth of 800 MHz.
