The **MA02107AF-R13** is a specialized electronic component, typically categorized as a **Surface Mount Device (SMD)** high-frequency RF connector or a precision micro-coaxial switch. These components are predominantly used in wireless communication devices for signal testing and antenna switching. --- ### 1. Key Technical Specifications Below are the typical technical characteristics associated with this part number series: | Feature | Specification | | :--- | :--- | | **Component Type** | RF Coaxial Connector / Switch | | **Mounting Type** | Surface Mount (SMT/SMD) | | **Frequency Range** | DC to 6 GHz (Commonly used for Wi-Fi/LTE) | | **Impedance** | 50 Ohms | | **Durability** | ~500 to 1,000 Mating Cycles | | **Packaging** | Tape & Reel (indicated by the "R13" suffix) | --- ### 2. Functional Description The MA02107AF-R13 serves two primary purposes in a circuit: 1. **Signal Routing:** It acts as a bridge between the internal RF circuit and the antenna. 2. **Diagnostic Port:** When a probe is inserted into the connector, it mechanically breaks the connection to the internal antenna and diverts the RF signal to the test equipment. This allows engineers to measure the performance of the radio module without interference from the antenna. ### 3. Structural Components * **Housing:** High-temperature thermoplastic capable of withstanding reflow soldering temperatures. * **Center Contact:** Usually gold-plated copper alloy to ensure low signal loss and prevent oxidation. * **Outer Shell:** Stainless steel or plated brass for grounding and structural integrity. * **Switch Mechanism:** A mechanical spring contact that toggles between "Closed" (normal operation) and "Open" (testing mode). ### 4. Common Applications * **Mobile Handsets:** Smart phones and tablets for 4G/5G testing. * **IoT Modules:** Wireless sensors and smart home hubs. * **WLAN/Bluetooth:** Any device requiring FCC/CE emissions testing via a physical port. --- ### 5. Part Number Breakdown (Typical) * **MA02107:** The base series designator. * **AF:** Revision or specific plating/material configuration. * **R13:** Packaging code, usually indicating a **13-inch Reel** for automated pick-and-place assembly.
