https://community.nxp.com/t5/NXP-Designs/MRFX035H-S-Parameters/m-p/2162699#M1206 <P>I have a question regarding the S-parameters provided for the MRFX035:</P><P>I had used the S-paramters to match the MRFX035H to 300 MHz, but when I use the resulting circuit in real life, the matching is completely off. Are the S-Parameters provided on the web-page actually correct?</P><P>When I simulate the 230MHz reference board from the Datasheet using the S-parameters, the results show that it is matched for ~300 MHz. So something seems to be wrong there.</P><P>I'm using this file:</P><P>! 12/17/2018<BR />! Rev 0<BR />! MRFX035H S-Parameters<BR />!
