I don't know a whole bunch about microwave gear, so I need a little help. I came across a small box in a pile this evening and I don't have a clue what it is.
It's a T construct, with SMAs at both ends of the horizontal. The vertical end looks like it's terminated to gnd. Internal construction in a plate which connects all three terminals. Above and below the plate is a ceramic triangle with a circular black insert. Each plate of the outer case has a circular magnet the same size as the black insert on the ceramic plates, on the external side, and there is a U shaped steel clamp which covers the entire assembly.
This is probably a really easy question for some of you out there....what is it?
I also came across some K&L filters from my time at Cylink, but the website gave me no joy. When the sample says S/N 1, I don't expect much... I suppose I could just feed a signal through them and see where the outputs occur.... both series have 5787.5 embedded n the part number, so I'm thinking that's the center or cutoff frequency.

Ferrite circulator.
Black insert is ferrite
If one of the three ports is terminated, it¹s hooked up as an isolator.
