AWR1843BOOST: Dielectric constant measurement fixture

Part Number: AWR1843BOOST

Hi:

     In  AWR1843BOOST , there is a line like this. 

1.Is this used for impedance testing or Dielectric constant testing? 

2.Can you give  me the detail of the testing and the fixture details?

3. Why the line Line width  is not the same?

  • Hello ,

    These traces are used for impedance and trace loss measurements. We use probe tips to interface directly on these traces and we measure S11 and S22. The trace widths are tampered towards the end of the trace to allow for proper signal-ground spacing of the probes.

    Regards,
