多倍频程邻接通道多路器对前端信号起着分选的作用,故是 EW 系统的关键部件.本文介绍的是在500MHz 到26·5GHz 频段内,用悬浮衬底带状线(SSS)来实现宽频带,低耗,选择性良好的低通、高通、带通滤波器以及邻接通道多路器的研制进展,尤其是提高了带宽/通道并提高了边带选择性.该文还探讨了目前为在20MHz 到1·5GHz 的领域内提供良好的性能而采用集总元件设计的一批新颖的低耗,选择性好的宽带滤波器.
Multi-octave adjoining channel multiplexers play a role in sorting the front-end signals and are therefore the key components of the EW system. This paper describes the use of suspended substrate striplines (SSS) in the 500 MHz to 26.5 GHz band, So as to realize the research and development of low-band, high-pass, band-pass filters and adjacent channel multiplexers with wideband, low power consumption and good selectivity, especially improving the bandwidth / channel and improving the sideband selectivity. A number of novel low power, selective wideband filters are now being designed for lumped components to provide good performance in the 20 MHz to 1.5 GHz area.
