Hello,

I am wondering if I can use some common op-amps that I have around to be used for impedance matching.

The transmitter is 75-Ohms and receiver is also 75-Ohms.

I need impedance matching because I would like to use an 100-Ohm CAT5e ethernet cable to transfer the signal between the 75-Ohm transmitter and receiver.

Here are some Op-Amps that I have:

LM386

NE5532P

UA741

OP07

I read that Op-Amp impedance matching can do the job but not sure if this is true.

Also would like to know if there are any circuit diagrams or tutorials on how to build such circuit.

The transmitter analog signal is a CCTV HD camera and the receiver converts converts analog signal to digital HDMI.

Here is some info about the analog signal (I am using HD-CVI):
