I'm sure others will have more useful suggestions, especially if you're planning to design your own, but I wanted to mention that I've had some success with filters from Mini Circuits - https://www.minicircuits.com/WebStore/Filters.html My experience/knowledge tends to end as soon as we hit the analog domain, so I have no idea how they perform compared to other suppliers or if they offer products for your more complex requirements. Thanks, Dominic
