14.2 BISM II PA Module without antenna (special order)
The dimensions for this module are identical to the standard BISM II PA illustrated above, but the
antenna is replaced with a U-FL connector.
The external antenna must provide a 50 Ohm impedance. The external antenna used must not result
in an increased output power. I.e. the total gain of mating connector, cable and antenna must not
exceed +2dB. If a higher gain antenna is connected, it will invalidate Bluetooth approvals for the
module as well as national RF compliance. Any change of antenna may require retesting of the RF
performance, to ensure that compliance is not affected. This is covered in more detail in application
note AN015 – Use of External Antenna with Wireless Modules.
The antenna connector is a U.FL connector, supplied by Hirose. Mating connectors with cables are
available from Hirose and their distributors, and also from other cable suppliers. The data sheet for
the connector series is available at http://www.hirose.co.jp/cataloge_hp/e32119372.pdf
