The **L4AS-1A2-R** is a specific electronic component within the category of high-performance coaxial connectors, manufactured by **CommScope** (Andrew Wireless Systems). It belongs to the **4.3-10 connector** family, which was designed to replace the larger 7/16 DIN connectors in modern wireless infrastructure. --- ### ## Technical Specifications Below is a breakdown of the electronic and mechanical characteristics of the L4AS-1A2-R: | Parameter | Specification | | :--- | :--- | | **Connector Type** | 4.3-10 Male | | **Body Style** | Straight | | **Cable Compatibility** | AL4RPV-50, LDF4-50A (1/2 in Coaxial Cable) | | **Impedance** | 50 Ohm | | **Operating Frequency** | 0 – 6000 MHz (6 GHz) | | **Passive Intermodulation (PIM)** | -161 dBc @ 700 MHz | | **Dielectric Withstand Voltage** | 2500 V | | **Interface Durability** | 100 cycles | --- ### ## Key Electronic Components & Materials The performance of the L4AS-1A2-R is determined by the materials used in its construction, which minimize signal loss and interference. * **Inner Contact:** Usually made of **Silver-plated Brass or Beryllium Copper**. Silver provides the highest electrical conductivity and minimizes skin-effect losses at high frequencies. * **Outer Contact:** **Trimetal plated Brass**. The "Trimetal" (usually an alloy of copper, tin, and zinc) provides excellent corrosion resistance and electrical shielding. * **Dielectric (Insulator):** Made of **PTFE (Polytetrafluoroethylene)**. This material has a low dielectric constant, ensuring minimal energy absorption and maintaining consistent 50-ohm impedance throughout the connector. * **Gasket/Seal:** Silicone rubber, providing an **IP68 rating** to prevent moisture ingress which could cause impedance mismatches or corrosion. --- ### ## Applications and Advantages The L4AS-1A2-R is primarily used in telecommunications, specifically for: 1. **Macro Cells & Small Cells:** Connecting remote radio heads (RRH) to antennas. 2. **Distributed Antenna Systems (DAS):** Providing high-quality signals in indoor environments. 3. **Low PIM Requirements:** The 4.3-10 interface is specifically designed to minimize Passive Intermodulation, which is critical for 4G LTE and 5G NR networks to prevent self-interference. ---
