Sorry forgot to mention high pass filters. I don’t think you will find anything in wr-28.
I did find some wr-28 style flange, but wr-22 band pass filters centred on 50GHz a while ago. But not any lately. 1296 is good idea for IF though, it would make a home constructed filter easier.

Do you have a photo off this switch?
And i wonder if any one made a highpass
filter in WR28 waveguide for 47ghz?
I want to use 1296mhz as IF
Thank you for reply...

Ray via groups.io:
Barry, I need to draw it really. However if you look down on the
switch, with the antenna port at 12.00. The mixer rf port is on
the 3.00 wg switch port. The wg 6.00 port connects to waveguide
going round to the mixer LO port. The Multiplier connects to the
switch 9.00 port.
Tx . the LO links to Ant port.
RX . Ant connects to mixer RF, plus the Multiplier connects
via waveguide to mixer LO port.
I hope that makes sense

I don't understand
how you are configuring the WG switch to do that? I
assume it is a standard 4 port switch without the thru
position? Can you explain a little more?
