1. Overview

RF (Radio Frequency) and IF (Intermediate Frequency) accessories are critical components for signal transmission, processing, and system integration in wireless communication systems. RFID (Radio Frequency Identification) accessories enable non-contact data exchange between tags and readers. These components are essential in telecommunications, IoT, logistics, and industrial automation, driving efficiency and connectivity in modern technology.

2. Main Types and Functional Classification

3. Structure and Components

RF accessories typically include conductive elements (e.g., brass or beryllium copper for connectors), dielectric materials (PTFE insulation), and protective housings (aluminum or plastic). RFID tags consist of a microchip, etched antenna, and substrate (PVC or PET). Advanced designs integrate EMI shielding and waterproofing for harsh environments.
