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.
1 In an FM (frequency modulation) transmitter the frequency of the carrier is varied by the modulation signal. 2  In an FSK (frequency-shift keying) transmitter, which transmits digital data, the frequency of the carrier is shifted between two frequencies which represent the two binary digits, 0 and 1. radio transmitter is an electronic circuit which transforms electric power from a battery or electrical mains into a radio frequency alternating current, which reverses direction millions to billions of times per second.
