摘要

Software-defined radio chip sets are becoming increasingly available for a wide variety of RF bands including the industrial, scientific, and medical (ISM) bands. Efficient operation of systems like these typically requires high-performance, multifunctional RF filters to enable preselection of the signals of interest while suppressing undesired interferers and noise. To fulfill these requirements and ensure high-quality transmission of the desired signal within a range of ISM bands using a single compact signal path, miniaturized and highly selective bandpass filters (BPFs) with broadband switching/tuning capabilities need to be developed.
