Mount these devices with the red mark facing
up.
It is recommended that the designer leave available
slots for a "pi" (or shunt-series-shunt) network. The
antenna matching network values in this datasheet are
only used when antenna is mounted on Johanson's
evaluation board. The matching values on client’s PCB
will be different. Go to:
http://johansontechnology.com/tuning and see how to
obtain the new values.
