The coilcraft part number is: JA4220-ALB. Iordered two of them and they were sent as free samples. You might want to buy some slightly bigger ones. I found them so small it was very hard to solder the coax cable to the connectors. Since I got them, I managed to damage one as they are quite fragile! In the confirmation email I got there was some contact info which may be useful for you: "For help, contact Victoria Berner at 847-516-5551 email@example.com " BTW every time I use this forum I'm told that my password is not valid. Each time I reset it according to the "Lost pasword preceedure. Then I can log on again. Its quite annoying.
I am looking at Sensl SiPMs as well, can you send the part number from Coilcraft?
I needed a fast pulse inverter in order to feed signals from the recent SensL SiPMs into a conventional CFD which only accepted negative signals. I got a very small ferite torridal transformer from Coilcraft and wired up to invert signals then inserted into in 50 ohm coax cable and it works fine. These things cost only a few cents each!
Thanks, that looks just fine.
Here is one (SI 100): https://www.picoquant.com/products/category/accessories/adapters-splitters-cables-various-accessories-for-photon-counting-setups
Ok, thanks! do you know an easy in-line inverter like mini-circuit or digikey? Can also redesign the detector I gues to produce positive signals, just it might be easier if there was a simple inverter if you are aware of? thanks Abaz
No. You have to use an inverter for one of your signals.
I would like to be able to trigger in this fashon: channel 0 > 0.1 and. channel 1< -0.1, because I have a positive and a negative signal. Can DRS4 (5) Eval board do this kind of trigger?
