    cyrf layout question

    federico.fuga

       Hi,

         

       

         

      I am developing an application using a psoc core and a cyrf7936 transceiver.

         

      I have taken a look to the cyfi first touch kit (CY3271) and studied the schematics (Reference design).

         

      I have opted for the External Power Amplifier solution and using two RF switch across the Amplifier/Saw filter section.

         

      I am new in RF design. I know that RF lines should be Impedence controlled and his layout should be very carefully designed. 

         

      But... should only the terminating line between the last switch (TX/RX) and the antenna be controlled or all the connection till the cyrf?

         

      I would say, only the part from the switch / amplifier to the antenna, but I am not sure.

         

      Thank you in advance.

         

       

         

      Regards
