Introduction
11_SMA-50-2-5/111_NE High-Reliability SMA Coaxial Connector
50Ω Impedance, Low Signal Loss, Ideal for RF Communication, Test Instruments & Industrial Electronic Systems
The 11_SMA-50-2-5/111_NE is an 11-channel RF coaxial component with industry-standard SMA interfaces, engineered for high-frequency signal transmission, distribution, and interconnection in RF systems. Optimized for 50Ω characteristic impedance—the universal standard for RF applications—it adheres to the "5/111" mechanical specification for precise form-factor compatibility.
Core Functional Characteristics
- 11-Channel Independent RF Signal Management: Supports simultaneous transmission of 11 discrete RF signals via dedicated SMA ports, reducing PCB footprint in systems requiring parallel RF paths.
- SMA Standard Compliance: Features SMA connectors with 1/4-36 UNC threaded interfaces for secure mating and compatibility with SMA-compliant equipment.
- 50Ω Impedance Matching: Precisely tuned to minimize signal reflection, ensuring efficient power transfer and consistent signal integrity up to 18 GHz.
- Enhanced Signal Isolation: Each channel is shielded to reduce crosstalk (< -40 dB at 1 GHz) and electromagnetic interference.
