“…At present, with the development of information technology, the magnitude of information transmission is rapidly increasing and the frequency band occupied is also becoming wider [1][2][3][4][5]. Ensuring electromagnetic isolation between different communication systems and ensuring that each communication system does not interfere with each other's normal operation has become increasingly important.…”

A bandwidth intelligent tunable filter based on filter theory is designed in this article. By selecting a special interstage coupling structure and using a varactor circuit, dual frequency band tunable transmission could be achieved within the broadband range. The final design results show that the insertion loss of the filter is reduced to below 1.65dB and the return loss is greater than -15dB. In addition, the fixed frequency of the filter is 290MHz and the bandwidth is greater than 5MHz. The adjustable operating frequency ranges from 228-275.7MHz, the bandwidth is greater than 4.5MHz and the insertion loss is not greater than 1.2dB. The above parameters meet the filter requirements. This filter could achieve effective signal filtering in communication systems, which could ensuring system electromagnetic compatibility.
