RF Transceiver ICs are semiconductor devices that consist of a transmitter and a receiver in a single package. Transceivers are designed to function proficiently within an RF family or standard such as AISG, Bluetooth, ISM, VHF, Wi-Fi, cellular, RADAR, 802.15.4 and Z-Wave. They are further classified by the type of modulation and the specific protocol versions. Some ICs include a built-in microcontroller.
