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.
