Description
The QLA series is a quick-disconnect version of the standard SMA interface, designed to meet the increasing density and assembly speed requirements of modern RF systems. This male (plug) variant is optimized for the 5mm (0.195″) cable class, including the flexible RG58, high-performance RG142, and low-loss LMR195/LMR200 series. The QLA interface utilizes a snap-on coupling mechanism that replaces the traditional threaded coupling nut, allowing for significantly faster installations and 360-degree cable rotation after mating to eliminate mechanical stress on the cable and the connector.
Maintaining a strict 50-Ohm impedance, this connector provides excellent electrical performance up to 6 GHz. It utilizes a professional dual-crimp termination system for both the center pin and the outer ferrule, ensuring a gas-tight mechanical bond and superior pull-off resistance. Manufactured with a gold or nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers high shielding effectiveness and protects sensitive RF data streams from electromagnetic interference (EMI) in congested rack environments.
Key Technical Advantages
-
Quick-Snap Coupling: The tool-free snap-on mechanism reduces installation and testing time significantly compared to threaded SMA connectors, making it ideal for high-port-count equipment.
-
360° Cable Flexibility: Once mated, the connector can rotate freely, allowing for easier cable management and reducing the risk of torque-related damage to internal solder joints or the cable dielectric.
-
5mm Cable Precision Matching: Specifically calibrated for RG58, RG142, and LMR195/200 series, ensuring an optimized electrical transition and minimal return loss.
-
High-Density Integration: The compact footprint and lack of a coupling nut allow for closer spacing between connectors on equipment panels and modular hardware.
-
Industrial Dual-Crimp Design: Provides maximum pull-off resistance and repeatable electrical performance, ensuring long-term reliability in cellular base stations and defense systems.
