THMA16: A Tuning Technique for Enhancing Far-Band Rejection Performance in Suspended Substrate Low Pass Filters

Presentation Abstract
Low pass filters are crucial for eliminating unwanted high-frequency signals in communication systems. Achieving enhanced far-band rejection while maintaining a compact design, however, remains a significant challenge. This presentation explores a practical tuning technique to enhance the far-band rejection capabilities of suspended substrate low pass filters. Despite the wideband nature of suspended substrate technology in general, achieving far-band rejection performance can be challenging due to the limitations inherent to transmission lines for wider frequency ranges. The tuning technique discussed aims to address these limitations, ultimately giving designers a practical option to extend far-band rejection performance in low pass filters.
