*This terminal must be soldered for anchoring and functionality purposes
Mounting Considerations I
Mount these devices with maroon 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 shunt-series-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, such as needing the layout file of the above, contact our RF Applications Eng. Team at:
