The **MA22TAG-R** is a specific RFID (Radio Frequency Identification) electronic component, typically utilized in asset tracking, logistics, and inventory management. It is designed to be a high-performance, durable tag compatible with standard RFID reading infrastructure. Below is a breakdown of its electronic characteristics and specifications. --- ### ## Technical Specifications The internal electronics of the MA22TAG-R are centered around an integrated circuit (IC) and an antenna etched onto a substrate. | Feature | Specification | | :--- | :--- | | **Operating Frequency** | UHF 860MHz – 960MHz (Global Standard) | | **Air Interface Protocol** | EPCglobal Class 1 Gen 2 / ISO 18000-6C | | **Memory Configuration** | 96-bit to 128-bit EPC; 32-bit User Memory (Typical) | | **Read Range** | Up to 5–10 meters (depending on reader power) | | **IC Type** | Often utilizes Impinj Monza or Alien Higgs series chips | | **Mounting Type** | Adhesive backing or mechanical fastening | --- ### ## Electronic Components Overview #### 1. Integrated Circuit (IC / Chip) The "brain" of the tag. It contains the logic to handle the communication protocol and non-volatile memory to store the unique identification numbers. * **Power Source:** It is **passive**, meaning it has no battery. It harvests energy from the electromagnetic field generated by the RFID reader. * **Data Protection:** Includes password-protected Access and Kill commands to prevent unauthorized tampering. #### 2. The Antenna The antenna is the largest electronic part of the MA22TAG-R. * **Design:** Usually made of etched aluminum or copper. * **Function:** It captures the RF signal from the reader, converts it into electricity to power the chip, and backscatters the response signal. #### 3. Impedance Matching Circuit Between the chip and the antenna, there is a micro-circuit designed to match the impedance. This ensures maximum power transfer from the antenna to the IC, which is critical for long-range reading. --- ### ## Environmental and Physical Design While not purely "electronic," the packaging is essential for the electronics to function in harsh environments: * **Substrate:** The electronics are mounted on PET (Polyethylene terephthalate) or a similar durable polymer. * **R-Designation:** The "-R" often signifies **Ruggedized** or **RoHS compliant** (Restriction of Hazardous Substances), indicating the parts are lead-free and encased in a protective housing to resist moisture and impact. ---
