SR4L002 antenna matching examples
Dear Sir,

We are using SR4L002 antenna in one of our designs for the European Union project, we need only to have a matching examples to start with and finally match our PCB our self using a system analyzer. Our board is capable of communication in 2G, Edge, LTE-M and NB-iOT.

Thank you very much,

Hello Francisco,

Page 20 of the data sheet has the starting values for the matching components.

The return to ground should have a 15nH inductor to ground.

From the antenna to the radio their should be a shunt 15nH inductor, a series 2.2pF capacitor, a series 3.3nH inductor and a 0.5pF shunt capacitor.

Best regards,

Geoff S.
