Introduction
16_SMA-50-2-111/133_NE
The 16_SMA-50-2-111/133_NE is a 16-channel RF coaxial component featuring SMA interfaces, designed for high-frequency signal transmission, distribution, and connection in RF systems. It adheres to the industry-standard SMA connector specification and is optimized for 50Ω characteristic impedance—the dominant standard in RF communication, test & measurement, and industrial high-frequency applications.
Core Functional Characteristics
- 16-Channel Independent RF Signal Handling: Supports simultaneous transmission or distribution of 16 independent RF signals via dedicated SMA interfaces, minimizing crosstalk between signals.
- SMA Standard Compatibility: Features industry-standard SMA connectors with 1/4-36 UNC threaded interfaces for secure, repeatable mating.
- 50 Ω Characteristic Impedance Matching: Optimized for 50Ω impedance, minimizing signal reflection at interfaces for efficient power transfer.
- Low Crosstalk & Signal Isolation: Each channel is electrically and physically isolated (typical crosstalk < -40 dB at 1 GHz between adjacent channels).
