Hi,

I've got a number of 3-port devices labeled SMC CHK-705S and others labeled SMC CHK-703S. I suspect they are mixers, but does anyone know specs or who the manufacturer is? Presumably SMC, but I don't know what that is.

Also in question, I have 3-port (3'rd terminated) Ditom DF5846 (prob isolator) and CTT's APM/080-2419.

I also have what appears to be a mini-circuits image reject mixer that's labeled Pulsar IR-F2-412 0122

Or a 3-port TRAK circulator 50A3001? any info and specs would be greatly appreciated. Thx, Jimmy
