RX2A Datasheet, PDF (5/7 Pages) Radiometrix Ltd – UHF FM receiver module with RSSI

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 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.
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.
