RF/IF (Radio Frequency/Intermediate Frequency) and RFID (Radio Frequency Identification) evaluation and development kits are essential tools for designing, testing, and optimizing wireless communication systems. These kits enable engineers to prototype hardware, validate protocols, and ensure compliance with industry standards. RFID systems utilize electromagnetic fields to automatically identify and track tags attached to objects, while RF/IF components handle signal processing between antennas and baseband systems. These technologies are critical in IoT, supply chain management, automotive systems, and healthcare.
