RF Module with ruler for size reference. An RF module (radio frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices.In an embedded system it is often desirable to communicate with another device wirelessly.n RF transmitter module is a small PCB sub-assembly capable of transmitting a radio wave and modulating that wave to carry data. Transmitter modules are usually implemented alongside a micro controller which will provide data to the module which can be transmitted.
For other uses, see RF (disambiguation). Radio frequency (RF) is any of the electromagnetic wave frequencies that lie in the range extending from around 7003300000000000000â 3 kHz to 7011300000000000000â 300 GHz, which include those frequencies used for communications or radar signals. RF usually refers to electrical rather than mechanical oscillations.
