I had same WR-90 laying around so I thought I would try and build a BPF for 10GHz.
I came across this design by W1VT.
The design uses a small piece of WR-90 and some small hardware which should be easy to obtain.
After a quick tune I found that the probe length has large effect on the filters frequency.
The filter has a bandwidth of around 80-90MHz and a loss < 1dB.
