Need help on circulator

[sv1437]

Hi ,

I have a circulator in my lab from "Advanced Microwave Labs" with the model number: AMF-2727.

But nothing is mentioned regarding the frequency range of operation or the power level it can handle.

I tried to search in google, but could not find. Could anyone of you help with this. Thanks,

This is about 20 years old product, so even if somebody is telling you the frequency range would be indicated to measure yourself its characteristics using a Network Analyzer.
For power handling the dimensions can give you a rough idea, especially for old circulators. Nowadays small circulators can handle higher power, because they use better quality ferrites.

Thank you vfone, it has N-type female ports. I can determine the frequency range using a Network Analyzer. But I think, determining the power handling capability is difficult.

Do you have any suggestions for that ?

No, I don't think is a non-destructive solution to find this. You can increase the power until the in-band insertion loss goes higher, but doing this you damage the internal ferrite.
Check on the net for similar products like the one below:

Usually the max power of old circulators goes in steps as: 10W, 30W, 100W, 300W...and so on.
