RFID, RF Access, Monitoring ICs

1. Overview

RF/IF (Radio Frequency/Intermediate Frequency) and RFID (Radio-Frequency Identification), RF Access, and Monitoring ICs are semiconductor devices critical to wireless communication, data acquisition, and system management. These ICs enable wireless connectivity, secure identification, and real-time monitoring in applications ranging from industrial automation to consumer electronics. Their importance has surged with the growth of IoT, smart infrastructure, and contactless technologies.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
