Mount these devices with mark facing up. Units: mm
* Line width should be designed to provide 50 impedance matching characteristics.
Note: It is recommended that the designer
leave available slots for a "pi" (or shunt-series-
shunt) network. The antenna matching network
values here are used when antenna is
mounted on Johanson's evaluation board. The
matching values and topology on clinet's PCB
will be different.
