 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
