433mhz rf module transmitter and receiver datasheet

They are sometimes used to replace older infrared communication designs as they have the advantage of not requiring line-of-sight operation. RF modules are most often used in medium and low volume products for consumer applications such as garage door openers, wireless alarm or monitoring systems, industrial remote controls, smart sensor applications, and wireless home automation systems. For these reasons, design engineers will often design a circuit for an application which requires radio communication and then 'drop in' a pre-made radio module rather than attempt a discrete design, saving time and money on development. Finally, radio circuits are usually subject to limits on radiated emissions, and require Conformance testing and certification by a standardization organization such as ETSI or the U.S. In addition, reliable RF communication circuit requires careful monitoring of the manufacturing process to ensure that the RF performance is not adversely affected. Good electronic radio design is notoriously complex because of the sensitivity of radio circuits and the accuracy of components and layouts required to achieve operation on a specific frequency. RF modules are widely used in electronic design owing to the difficulty of designing radio circuitry. RF modules are typically fabricated using RF CMOS technology. RF communications incorporate a transmitter and a receiver. For many applications, the medium of choice is RF since it does not require line of sight. This wireless communication may be accomplished through optical communication or through radio-frequency (RF) communication. In an embedded system it is often desirable to communicate with another device wirelessly. RF module (with a ruler for size reference)Īn RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices.
