change impedance and level

[alipio]

Hi all
Is there some signal conditioning module to change a 16 Mhz square 5 V 24 Kohms signal to a 5 V 75 Ohms?
And same input signal for an output of 1 V 75 ohms?

If not, somebody can post schematics of circuits to do that?

Thanks in advance

Hi!

I'm not aware of any "off-the-shelf" solution for that.
However, the easiest way to do that is probably using an operational amplifier in non-inverting mode as a buffer circuit.
The buffer should be terminated with a 75 Ohm resistor to match the required impedance. Make sure to select a unity gain stable op-amp
to avoid oscillations.
For the 1V output, you need to change the feedback resistor to attenuate your signal down to 1 V.
I don't have a schematic for you, but if you type in op-amp in www.google.com, there is a ton of stuff out there.

Best,
