If you need designs for edge-coupled bandpass filters on alumina substrate, Exceed Microwave has a long list of filters you can choose from. We will provide you with .dxf or .step file which you can use to fabricate your filters.
Simulation plots are generated using HFSS and if you don’t see what you need, we’ll design it for you.
Some 4 section filter designs are available for free so you can evaluate our designs. For more information visit www.exceedmicrowave.com
