 30 Dec 2004 2:40 about the split the analog signal |
|
|
|
| I have a problem, that is I want to sent an analog signal to more ADCs (may be four ADCs). The analog signal is dc to 2GHz. Can I using the PCB layout to split the analog signal? How about the "power splliter" in mini-circuits. can I use the power spllitter to split the analog? please give me an idea, with great thanks.

Normally I would use a buffer for each ADC.
In your case, however, I just can't imagine how are you going to handle this wide bandwidth (0 - 2GHz)?
Here is an example of 1MHz-2GHz power splitter. These devices will not work with DC!!!

I am just curious. May I ask what type of signal you're working with that requires a bandwidth from Dc to 2ghz?
Just an academic curiosity.
