RF/IF (Radio Frequency/Intermediate Frequency) and RFID (Radio Frequency Identification) accessories are critical components in wireless communication systems. These accessories enable signal transmission, reception, and processing in RFID systems, which utilize electromagnetic fields to automatically identify and track tags attached to objects. Their importance spans industries such as logistics, healthcare, and manufacturing, where automated data capture and asset management are essential.
| Type | Functional Features | Application Examples |
|---|---|---|
| RFID Antennas | Transmit/receive RF signals, impedance matching, directional/radiation pattern control | Warehouse inventory tracking, vehicle access control |
| RFID Readers/Modules | Encode/decode data, protocol handling (ISO 14443, EPC C1G2), interface with host systems | Retail point-of-sale systems, medical asset management |
| RFID Tags | Passive/active memory storage, unique ID encoding, environmental sensing (optional) | Supply chain logistics, livestock tracking |
| RF Connectors/Cables | Low-loss signal transmission, waterproofing, vibration resistance | Industrial automation, outdoor communication towers |
| RFID Isolators/Circulators | Signal direction control, reflection suppression, power protection | High-power RFID readers, military communication systems |
Typical RFID accessories consist of:
Example: An RFID antenna combines etched metal traces on a PCB substrate with impedance-matching circuitry and an IP67-rated housing.
| Parameter | Description | Importance |
|---|---|---|
| Frequency Range | Operating band (e.g., 860-960 MHz UHF, 13.56 MHz HF) | Determines regulatory compliance and application compatibility |
| Impedance | Characteristic resistance (typically 50 ) | Ensures maximum power transfer between components |
| Power Handling | Maximum RF input (e.g., 20W for readers) | Prevents component damage from signal overload |
| Insertion Loss | Signal attenuation (e.g., <0.5dB for cables) | Impacts system read range and reliability |
| Read Range | Operational distance (e.g., 0-15 meters) | Defines deployment flexibility |
| Manufacturer | Representative Product | Features |
|---|---|---|
| Impinj | R420 UHF Reader | Supports 860-960 MHz, 4-port, integrated FPGA |
| Alien Technology | ALR-FX100 Reader | Compact form factor, EPC Class 1 Gen 2 compliance |
