Description

technical field [0001] The invention relates to the field of electrothermal simulation, in particular to a cavity filter electrothermal coupling simulation test method, equipment and medium. Background technique [0002] A filter is a two-port network that is frequency selective, allowing certain frequencies to pass through while blocking others. Common filters include spiral oscillator filters, microstrip filters, interdigitated filters, etc. Although their design methods have their own special features, these design methods are still based on low-frequency synthesis method filter design. With the development of communication technology, multi-frequency working scenarios of filters are becoming more and more common, and the requirements for separation frequencies are also increased accordingly, especially the anti-interference requirements for adjacent channels are becoming more and more stringent, which makes it difficult for common filters to satisfy. Cavity filter is a...
