The part number **W2AC-AZBA-R2/Q** refers to a high-performance **External Dipole Antenna** (often used with Wi-Fi modules and industrial wireless routers), typically manufactured by companies like **AzureWave** or utilized in conjunction with **Qualcomm** reference designs. Below is a detailed breakdown of its electronic specifications and characteristics. --- ### 1. General Specifications This antenna is designed for high-frequency wireless communication, specifically targeting the 2.4GHz and 5GHz bands. | Parameter | Specification (Typical) | | :--- | :--- | | **Antenna Type** | Dipole (Rubber Duck) | | **Frequency Range** | 2.4 - 2.5 GHz / 5.15 - 5.85 GHz | | **VSWR** | ≤ 2.0 | | **Peak Gain** | 2 dBi (2.4GHz) / 3 dBi (5GHz) | | **Impedance** | 50 Ohms | | **Polarization** | Linear, Vertical | | **Radiation** | Omni-directional | --- ### 2. Physical & Connector Characteristics The "R2/Q" suffix often denotes specific revision levels or packaging standards for integration into larger systems. * **Connector Type:** Typically **RP-SMA (Plug/Male)**. This is the industry standard for Wi-Fi equipment to comply with FCC regulations (Reverse Polarity). * **Hinge:** Usually features a 0°, 45°, and 90° adjustable knuckle for optimal signal orientation. * **Material:** TPE or ABS plastic radome for durability and UV resistance. --- ### 3. Electronic Design Components Internally, the antenna consists of several critical layers: 1. **Radiating Element:** A copper alloy or PCB-based dipole structure tuned to specific resonant frequencies. 2. **Sleeve:** A metallic tube (balun) that helps prevent current from flowing down the outside of the cable, maintaining the radiation pattern. 3. **Matching Network:** Passive components (LC circuits) integrated into the base to ensure the VSWR stays below 2.0 across the wide bandwidth of Wi-Fi 5 or Wi-Fi 6. --- ### 4. Typical Applications This part is commonly found in: * **Industrial Gateways:** Providing external connectivity for IoT nodes. * **Wi-Fi Access Points:** Used as the primary detachable antenna for MIMO configurations. * **Embedded Systems:** Connected via U.FL-to-RP-SMA pigtail cables to internal M.2 wireless cards.
