Matching Circuits2 2It is recommended that the designer leave available slots for a "pi" (or shunt-series-shunt) network, even if all slots won't be used, this will prepare the PCB for the final mass production values of the matching circuit. The antenna matching network values above are used when antenna is mounted on Johanson's evaluation board. The matching values on clients PCB will be different. Go to:
http://johansontechnology.com/tuning and see how to obtain the new values yourself if you have a network analyzer. www.johansontechnology.com 4001 Calle Tecate Camarillo, CA 93012 TEL 805.389.1166 FAX 805.389.1821 Ver 3.0 2015 Johanson Technology, Inc. All Rights Reserved
