Hello All,
Just joined this forum after finding it very useful for other questions I had. I am currently working on a simple project which involves designing a pimatching circuit for a source resistance of 50 ohms and load resistance of 800 ohms. The frequency of operation (center frequency) given to me is 800 MHz and bandwidth specification given to me is 25 MHz. From this information, I calculated my required Q factor and designed my pimatching networks. I have used the block DC format.
Using the .net and .ac commands, I simulated my S11 parameter to ensure it is less than 10 dB as that means good matching. The question is how do I interpret the S11 simulation? It just lines going up and down to me. In the attached file, I included the S11 plot and my schematic. My S11 is in the mdB range so I assume I have designed a good matching circuit?
Thanks for reading
