I am asking about a component called rosta or rotsu I am not sure , I have three PCB`s that are combined with each other and each baord needs a feeding supply voltage all the same of three volt
I am using a two 1.5 battries each one AA size and they are put in a holder ,
I was told this rosta works as a distrubutor , one input several outputs for the same voltage , is there such a thing and where can I purchase it
aslo , what is the adaptaer used for two wires to be transformed to an SMA male connector because I have one of my PCB has an SMA female connector for the DC and I need an SMA male connector to feed it
any help is higly appreciated

rosta? rostu? Did you hear it right, or is someone sending you on a snipe hunt?

Some component evaluation boards use SMA connectors for everything. This connector is normally for RF signals. Suggest you use a SMA to BNC adapter and then a BNC to binding post adapter.

If the SMA on your board is a female, use a SMA Male to BNC female adapter. Made by Pomona and available at as part number 501-1141-ND Plenty of other people make this adapter.

On that adapter, then use a BNC male to binding post. Made by Pomona and available at as their part number 501-1033-ND for $12.57 Data Sheet:
The Pomona BNC-to-Binding-Post part is also available at Mouser ( as their part number 565-1296
