The **M2CEC-1350B-R/Q** is a high-performance **Micro-Wave Coaxial Connector** assembly, typically categorized under radio frequency (RF) components. These parts are primarily used for high-frequency signal transmission in mobile devices, communication infrastructure, and testing equipment. Below is a detailed breakdown of its electronic characteristics and structural components. --- ## 1. Technical Specifications This component is designed to maintain signal integrity while minimizing electromagnetic interference (EMI). | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | RF Coaxial Connector / Cable Assembly | | **Impedance** | 50 Ohms (Standard for RF) | | **Frequency Range** | DC to 6 GHz (Typically supports Wi-Fi 6/6E bands) | | **V.S.W.R.** | 1.3 Max (at 3GHz) to 1.5 Max (at 6GHz) | | **Insertion Loss** | Low (typically < 0.5dB depending on length) | | **Mating Cycles** | ~30 to 100 cycles | --- ## 2. Key Electronic Parts & Materials The performance of the M2CEC-1350B-R/Q relies on the quality of its internal materials: ### A. Center Contact (Signal Path) * **Material:** Phosphor Bronze or Beryllium Copper. * **Plating:** **Gold plating** is used to ensure high conductivity and prevent oxidation over the lifespan of the device. ### B. Dielectric Insulator * **Material:** PTFE (Teflon) or LCP (Liquid Crystal Polymer). * **Function:** This part maintains the precise spacing between the center conductor and the outer shell to ensure a constant **50-ohm impedance**. ### C. Outer Shell (Grounding) * **Material:** Copper Alloy with Gold or Silver plating. * **Function:** Acts as the electrical ground and provides **EMI shielding** to protect the signal from external noise. ### D. Coaxial Cable * The "1350" in the part number often refers to the specific cable diameter or length configuration (e.g., 1.37mm or 1.13mm micro-coax). --- ## 3. Physical Attributes The suffix **-R/Q** usually denotes specific packaging or orientation standards: * **R (Reel):** Indicates the parts are supplied on a reel for automated SMT (Surface Mount Technology) pick-and-place machines. * **Q (Quality/Orientation):** May refer to a specific mating orientation or a "Quick-lock" mechanism. ### Structural Diagram Representation ```text [ Outer Jacket ] -> Protection [ Outer Shield ] -> Grounding / EMI Shielding [ Dielectric ] -> Impedance Matching [ Inner Conductor]-> Signal Transmission (Gold Plated) ``` --- ## 4.
