A balun with 2 SMA differential input and one single balanced output ?
Normally you should build it up by yourself on a PCB but if you want to use builded one, you'll pay more..
For instance...

Thanks bigboss. this is very helpful.

Picosecond Pulse Labs sell them! They do one 200 kHz - 17 GHz. I'd like to know how they get such a frequency coverage, but I'm not going to buy one to open it up.

My experience with that company before is they sell excellent products, but they are not cheap. I've never bought a balun from them, but one of their bias-T's was used in my PhD project, and I've used other products from them too.

Dear BigBoss,

This balun is just what I want. But it seems the compay does sell the product directly.
Do you konw where I can buy it. I am in Hong Kong.
Is there agency or market?

Best regards,

Thanks Dave. but this one is more than I need. I guess it must be very expensive.
