NTAGI2C Questions

Have a project in prototype with the NT3H2XXX.  The chip is working, and we refine the application.  Two questions have surfaced, and I would appreciate some help getting answers.

  1. What is the nominal value of the tuning capacitor for a Class 6 antenna?  ( We do not have the expertise to characterize the antenna. )
  2. We have 10uF of bypass capacitance on the VCC in an energy harvesting application.  The application runs fine with it, but the data sheet recommendation is 0.22uF.  We are using a passthrough mode only and do not shut down the reader’s RF field as a part of operation.  Is the 10uF of bypass capacitance okay?
