Type Approval requirements: Europe
The modules comply with the requirements of the R&TTE Directive (including standards EN 300 220-3
and EN 301 489-3) when used in accordance with the information contained herein. The following
provisos apply:
1) The modules must not be modified or used outside their specification limits.
2) The modules may only be used to transfer digital or digitised data. Analogue speech and/or
music are not permitted.
3) The equipment in which the BiM3B is used must carry all necessary external labelling to meet
the requirements of the R&TTE directive.
4) The BiM3B has not been tested with antennas having gains greater than that of a quarter-wave
whip. The use of such antennas may require further R&TTE approval.
Module mounting considerations
Good RF layout practice should be observed. In particular, any ground return required by the antenna
or feed should be connected directly to the RF GND pins at the antenna end of the module, and not to
the OV pins which are intended as DC grounds only. All connecting tracks should be kept as short as
possible to avoid any problems with stray RF pickup.
If the connection between module and antenna does not form part of the antenna itself, it should be
made using 50Ω microstrip line or coax or a combination of both. It is desirable (but not essential) to fill
all unused PCB area around the module with ground plane.
