The **MA23FCX-R** is a specialized high-performance RF (Radio Frequency) connector, specifically an **SMA (Sub-Miniature version A) Jack for PCB mounting**, manufactured by Hirose Electric. It is designed for high-frequency applications, typically found in telecommunications and measurement equipment. --- ### 1. Key Technical Specifications The electrical and physical properties of the MA23FCX-R are critical for maintaining signal integrity in RF circuits. | Feature | Specification | |:---|:---| | **Connector Type** | SMA Jack (Female) | | **Mounting Type** | PCB - Through Hole / End Launch | | **Impedance** | 50 Ohms (Standard) | | **Frequency Range** | Up to 18 GHz (Typical for SMA) | | **Contact Plating** | Gold (for low resistance and corrosion prevention) | | **Termination Method** | Solder | --- ### 2. Physical Construction The "R" suffix often indicates compliance with environmental standards or a specific packaging/orientation variation (like RoHS compliance). * **Body Material:** Usually Stainless Steel or Brass with Gold plating to ensure durability and high conductivity. * **Dielectric:** PTFE (Teflon) is standard for SMA connectors to maintain the constant 50-ohm impedance and provide thermal stability during soldering. * **Center Contact:** Beryllium copper or similar high-strength conductive alloy, gold-plated. --- ### 3. Applications Due to its high frequency and precision, the MA23FCX-R is commonly used in: * **Wireless Infrastructure:** Base stations and antennas. * **Test & Measurement:** Oscilloscopes and signal generators. * **Aerospace:** High-reliability communication modules. * **Medical Equipment:** Imaging systems requiring high-speed data transmission. --- ### 4. Mounting Considerations When designing a PCB for the MA23FCX-R, engineers must focus on: 1. **Impedance Matching:** The PCB trace leading to the connector must be designed as a 50-ohm microstrip or stripline. 2. **Solder Reflow:** The gold plating is compatible with most reflow or manual soldering processes, but heat must be managed to avoid melting the internal PTFE dielectric.
