Cavity Duplexer Tuning with 1d Resnet-like Neural Networks

In wireless communications it is important to filter or combine/separate signals in a specific range of frequencies. Such devices are called filters and duplexers, respectively. In the microwave domain they use phenomena of electromagnetic resonance in circuits that include multiple capacitances and inductances created with a number of coupled cavity resonators to pass or reject specific frequencies and therefore referred as "cavity" filters/duplexers. They are manufactured as metallic boxes with few connectors (2 for a filter and 3 for a duplexer). Due to small imperfections in the assembly of the enclosure, the frequency response varies from one device to another.
