Module mounting considerations
The module may be mounted vertically or bent horizontal to the motherboard. 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 pin at the antenna end of the module, and not to the OV pin which is intended as a DC ground
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
50 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.
The module may be potted if required in a viscous compound which cannot enter the screen can.
Warning: DO NOT wash the module. It is not hermetically sealed.
