Note:
The PCB strip antenna is available from Ethertronics with or without adhesive tape
backing for mounting to a plastic case. The antennas Lantronix supplies include an
adhesive backing. For the component without tape backing a non-conductive double
sided adhesive tape can be used to fix the antenna in place. The Ethertronics part
numbers listed above come with a 50 mm U.FL cable attached to the PCB strip antenna.
The 50 mm cable length is the minimum allowed cable length for use with the
PremierWave 2050. For similar PCB strip antennas with longer cables consult with
Ethertronics (
Lantronix provides a U.FL to Reverse SMA antenna cable in with the evaluation board and
sample kits for development work. These cables can be purchased from Lantronix for production
or supplied by an RF cable manufacturer. External antennas can be purchased from an antenna
vendor. Components for cable design should be selected for low loss over the entire 2.4 GHz to
5.9 GHz signal range. The cable target impedance should be 50 ohms.
