Where to get a WR05 to WR03 tapered transition?

[yx9393]

I was wondering if anyone knows where to find a tapered transition for G to J band for a spectrum analyzer? As in for a WR05 waveguide mixer to get from 140-220 Ghz to 220-325 Ghz.

If you've got or can afford equipment to reach those frequencies then you'd already know. Like the old adage "if you have to ask, you can't afford it".

Should be in the low thousands for the parts based on transitions in slightly lower bands.
