The **MRF01-R-1** is a high-performance, micro-miniature coaxial connector developed by **Hirose Electric**. It is primarily designed for high-frequency signal transmission in compact electronic devices. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Connector Type** | Micro-Coaxial (MCX style variant) | | **Impedance** | 50 Ohms (Standard) | | **Frequency Range** | DC to 3 GHz (Commonly used up to 6 GHz in specific iterations) | | **V.S.W.R.** | 1.3 Max (at 3 GHz) | | **Contact Resistance** | 15 mΩ Max (Center), 10 mΩ Max (Outer) | | **Durability** | 500 Mating Cycles | --- ### 2. Component Structure and Materials The "R-1" designation usually refers to the specific mounting style (Right Angle) or the gender of the connector. * **Center Contact:** Typically made of Brass or Phosphor Bronze with **Gold Plating** to ensure high conductivity and oxidation resistance. * **Insulator:** Uses PTFE (Polytetrafluoroethylene) or similar high-grade resins to maintain consistent impedance. * **Outer Shell:** Often Nickel-plated or Gold-plated Brass to provide shielding against EMI (Electromagnetic Interference). --- ### 3. Core Features 1. **Compact Size:** It is significantly smaller than standard SMA connectors, making it ideal for dense PCB layouts. 2. **Snap-on Coupling:** Features a "snap-on" mechanism that allows for quick mating and unmating without the need for threading tools. 3. **Broadband Performance:** Maintains low VSWR (Voltage Standing Wave Ratio) across a wide frequency spectrum. --- ### 4. Typical Applications The MRF01 series is commonly found in the following sectors: * **Wireless Communication:** WiFi modules, Bluetooth hardware, and GPS receivers. * **Mobile Devices:** Handheld scanners, smartphones, and tablets. * **Medical Equipment:** High-frequency imaging and monitoring sensors. * **Antenna Connections:** Internal routing from a PCB to an external antenna port. --- ### 5. Assembly and Mounting The **MRF01-R-1** is generally a **PCB-mount** component. * **Mounting Type:** Through-hole or Surface Mount (depending on the specific suffix variation). * **Soldering:** Requires precision soldering to avoid bridging the center signal pin with the outer ground shield.
