RF Modules

What is a RF Module?A RF Module is commonly referred to as a radio frequency module, it is a small electronic device that is used to transmit and receive radio signals between two devices. A RF Module is usually used with a pair of encoder/decoders. The encoder is used for encoding parallel data for transmitting whilst the reception is decoded by a decoder.What is the main function of a RF Module?Radio frequency modules are the biggest facilitator of wireless communication, this is because it does not require a line of sight. This is in contrast to its usual alternative, Infrared, which mostly operates in line of sight mode. It spans between a range of 3 KHz and 300 GHz, with the lower end being applied in applications such as submarines and radio stations whilst the higher spectrum is used in applications such as GPS, Wi-Fi, Bluetooth and TV broadcasting. Some of the main functions of a RF Module are: Act as a transmitter of signals A solution for detecting radio signals Bridging communication between two devices RF can stretch communication between applications Acts as a receiver module Acts as a transmitter Did you know?The performance of radio frequency applications is dependent on a few factors. Through increasing a transmitters power, a larger communication range can be attained. This also causes a power drain from the power source which could result in a shorter life span for battery powered devices. Through the use of higher transmitted power, an interference with other radio frequencies can occur.Typical Applications of a RF Module Car alarm systems Remote controls Sensor reporting Automation systems
