Hi fellow designers,
I know this has been asked before but I was not able to understand the actual difference.
I have designed the following single tuned amplifeir that should provide a 20 dB gain at 30 MHz to a 50 ohm load with a 1 MHz bandwidth.
Doing AC analysis proves that the amplifier complies with the specifications. However if I measure the S21 parameter , I get a different value that the AC analysis measured gain. I know that S21 provides power gain, but should the power gain in dB be the same as the voltage gain in dB?
I know that I have not understand correctly what S21 repsesents, so I hope you can help me.
Thank you in advance
