NRX0 Datasheet, PDF (7/8 Pages) Radiometrix Ltd – 27MHz HF Narrow Band FM TX & RX

Module mounting considerations
The modules may be mounted vertically or bent horizontal to the motherboard. Note that the components
mounted on the underside of the NTX0 and NRX0 are relatively fragile – avoid direct mechanical contact
between these and other parts of the equipment if possible, particularly in situations where extreme
mechanical stresses could routinely occur (as a result of equipment being dropped onto the floor, etc).
Good RF layout practice should be observed. 50Ω microstrip line or coax or a combination of both should be
used to connect RF pin of the module to RF connector or antenna. It is desirable (but not essential) to fill all
unused PCB area around the module with ground plane.
Variants and ordering information
The NTX0 transmitters and NRX0 receivers are manufactured on 27.095MHz as standard:
