Hi,
I'm trying to make an impedence matching circuit. My input resistance is 1,5K and my output load is 330 (see schematic below). To be sure that my circuit works, I put a probe after the 1,5K. I measure the voltage. Then I removed the load and I thought that I would get twice the voltage I measure previously. But, i measure a voltage less than the first voltage. I juste don't understand what is happening. By the way, I'm trying to match impedance at 455kHz. The input of the circuit will be the output of a SA612 (AM Mixer) and the load will be a resistor.
Thanks
Pat
