Description

technical field [0001] The invention relates to the field of wireless communication systems, in particular to a reconfigurable multifunctional filter based on a half-wavelength resonator. Background technique [0002] With the rapid development of modern wireless communication systems, spectrum resources are increasingly tight, and more and more environments require electronic devices used in them to be tunable and multi-functional, so as to improve the utilization of spectrum resources. Among them, the balun filter is an independent microwave passive device. It relies on the principle of anti-interference of the balanced circuit in the signal system. At the same time, the balun filter also has the advantages of low cost, high integration, and miniaturization. Therefore, The balun filter has become one of the keys to develop a radar communication system that is resistant to electromagnetic interference. [0003] In addition, the power divider is also an important component ...
