An external matching network is needed to transform the impedance to 50 ohm. Since the RX and TX impedance are very close to each other we can achieve a return loss better than -10 dB in both modes.&nbsp;</P><P></P><P>Best Regards,</P><P>Mario</P></BODY></HTML> Tue, 08 Aug 2017 05:53:37 GMT https://community.nxp.com/t5/Wireless-MCU/JN5169-impedance-value/m-p/674743#M3044 mario_castaneda 2017-08-08T05:53:37Z Re: JN5169 impedance value https://community.nxp.com/t5/Wireless-MCU/JN5169-impedance-value/m-p/674744#M3045 <HTML><HEAD></HEAD><BODY><P>Hi Mario,</P><P></P><P>Thanks for the support.</P><P></P><P>It will be really helpful to us.</P></BODY></HTML> Fri, 11 Aug 2017 04:45:52 GMT https://community.nxp.com/t5/Wireless-MCU/JN5169-impedance-value/m-p/674744#M3045 chirag_sharma 2017-08-11T04:45:52Z
