The **CONSMA007-R178** is a specialized electronic component, specifically a **Surface Mount Device (SMD) SMA Female Connector** designed for Radio Frequency (RF) applications. It is manufactured by Linx Technologies (now part of TE Connectivity). --- ### 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Connector Type** | SMA Female (Jack) | | **Mounting Type** | Surface Mount (SMD / SMT) | | **Orientation** | Right Angle | | **Frequency Range** | 0 to 12.4 GHz | | **Impedance** | 50 Ohms | | **Body Material** | Brass | | **Body Plating** | Gold | | **Contact Material** | Beryllium Copper | --- ### 2. Key Electronic Features #### High-Frequency Performance Designed to maintain signal integrity up to **12.4 GHz**, this connector is suitable for high-speed data transmission and microwave frequencies. Its **50-ohm impedance** is the industry standard for minimizing signal reflection (VSWR) in RF circuits. #### Right-Angle Configuration The "Right Angle" design allows the cable to be connected perpendicular to the PCB. This is crucial for: * Reducing the profile height of the device. * Managing cable strain in tight enclosures. #### Surface Mount Technology (SMT) Unlike "Through-Hole" connectors that require pins to pass through the PCB, the CONSMA007-R178 sits on the surface pads. This allows for: * Automated assembly via pick-and-place machines. * Simplified PCB routing on the opposite side of the board. --- ### 3. Common Applications This part is typically found in hardware where wireless connectivity is required: * **Wi-Fi Routers:** Connecting internal antennas to external ports. * **IoT Gateways:** For LoRaWAN, Sigfox, or Cellular (LTE/5G) connections. * **GPS Modules:** Providing a stable interface for active or passive GNSS antennas. * **RF Testing Equipment:** Used as a durable interface for testing signals on a production line. --- ### 4. Mounting Footprint (Typical) ```gcode (Top View Visualization) [ Pad 1 ] <-- Signal (Center Contact) [GND] [GND] <-- Outer Shielding/Grounding Pads [GND] [GND] ``` *Note: Proper grounding of the four outer pads is essential to shield the signal from EMI (Electromagnetic Interference).*
