Mounting Considerations I
Mount these devices with brown mark
facing up. *Line width should be
designed to provide 50 Ω impedance
matching characteristics.

**Note 2: It is recommended that the designer leave available slots for a "pi" (or shuntseries-shunt) network. The antenna matching network values above are 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. If you need further help, contact our RF Applications Eng. Team at:
