摘要
频率稳定性是微波滤波器的重要技术指标之一。保证频率稳定,对滤波器谐振腔进行温度补偿是较为有效的方法。主要探讨温度补偿新技术,对目前比较常用的几种微波滤波器的温度补偿技术进行阐述,并给出改进法来提高微波滤波器频率稳定性。随着广播电视及其通信技术的飞速发展,温度补偿技术必将随着市场需求的增加而获得更快发展。
Temperature compensation technologies on microwave filters are very important in microwave filters design. Promising a frequency stability, flapping a chamber to carry on temperature repair to the filters is more valid method. This text mainly inquiries into the temperature in expiation of new technique,and compensates a technical improvement to raise the frequency stability of the microwave filter currently to iner common use and a few temperatures of microwave filters. With the rapid development of radio and TV communication technique, the temperature compensation has fast development with increase in market demand.
