RF (Radio Frequency) and IF (Intermediate Frequency) transceiver ICs are integrated circuits that enable wireless communication by transmitting and receiving radio signals. These devices are critical in modern technologies, supporting applications from cellular networks to IoT (Internet of Things). RFID (Radio-Frequency Identification) RF transceivers specialize in short-range communication for identification and tracking systems. Their miniaturization, energy efficiency, and reliability have driven advancements in connectivity across industries.
