I have this LNA, it demands a BIAS-TEE power supply of 6V - 12V, the SDR I have cannot provide that much voltage, fortunately the LNA has space to solder a power pin or two wires.



Can anyone here suggest what kind of pin I can solder or should I just solder two wires. The specifications doesn't say how many amps and watts are required, what kind of 12V power supply can I use, are there anything I can build myself?

It says what a BIAS-TEE is, it doesn't tell me what kind of pin I should add?

What kind of pin would you solder, and are there any power adapters which supply 12 V?

I think that was confusing you a "biased tee power supply."
Any pin you wish to solder on the connection for the power supply or straight leads your choice. I would get a 9-volt battery using 9 volt battery connector solder the red lead to VCC and the black lead to ground directly to the pads.Or any wall wort (power supply)6 to 12 volts. and you're done.
I'm sure others can explain it more thorough than I to you. Do a little research on the internet. But I'm happy you came here first.
