b) With Matching Circuits 2.6 Note: It is recommended that the designer
leave available slots for a "pi" (or shunt-series-
3.9nH shunt) network. The antenna matching network
values here are used when antenna is
1.0pF 1.6 mounted on Johanson's evaluation board. The
matching values and topology on clinet's PCB
will be different.
