The **W2TS-0B1-R2/N** belongs to the **W2TS series**, which are high-performance, compact **GNSS (Global Navigation Satellite System) antennas** typically manufactured by companies like **Inpaq**. This specific part is an active internal patch antenna designed for precision positioning. --- ### 1. Key Technical Specifications The following table outlines the primary electronic characteristics of the W2TS series: | Parameter | Specification | Note | | :--- | :--- | :--- | | **Frequency Range** | 1575.42 MHz ± 1.02 MHz | Optimized for GPS L1 / GALILEO E1 | | **Supply Voltage** | 2.5V to 3.5V DC | Typical operating range | | **Current Consumption** | 7.0 mA (Max) | Low power consumption for mobile devices | | **LNA Gain** | 18 dB to 20 dB | Low Noise Amplifier integrated gain | | **Noise Figure** | 1.5 dB (Typical) | Ensures high sensitivity in weak signal areas | | **Output Impedance** | 50 $\Omega$ | Standard RF matching | --- ### 2. Physical Components & Construction The assembly of the **W2TS-0B1-R2/N** consists of several critical electronic layers: 1. **Ceramic Patch:** A high-permittivity dielectric ceramic element that captures the electromagnetic waves. 2. **Integrated LNA (Low Noise Amplifier):** A built-in circuit that boosts the weak satellite signals while keeping noise levels low before the signal enters the GNSS receiver module. 3. **SAW Filter:** Surface Acoustic Wave filter included to reject out-of-band interference (e.g., from LTE or WiFi signals). 4. **Connector & Cable:** The "R2" and "N" designations often refer to the specific cable length and connector type (commonly **U.FL/IPEX** or similar micro-miniature connectors). --- ### 3. Part Number Breakdown (Typical) While manufacturers vary slightly, the nomenclature usually represents: * **W2TS:** Series identifier (Active GNSS Patch Antenna). * **0B1:** Internal version or ceramic size (e.g., 10x10mm or 12x12mm). * **R2:** Revision or cable routing specification. * **N:** Connector type or packaging orientation (e.g., No connector vs. specific IPEX). --- ### 4. Application Use Cases Because of its small footprint and active amplification, this part is used in: * **IoT Devices:** Battery-powered trackers. * **Automotive:** Dash cams and telematics units. * **Drones:** Compact flight controllers requiring GPS lock. * **Wearables:** Specialized industrial handhelds.
