30W SMA Directional Coupler 0.5–26.5GHz 10dB Coupling with SMA Female Connectors

Product Overview:
Designed for ultra-wideband applications, electronic warfare (EW), defense systems, and high-frequency laboratory testing, our 30W SMA Directional Coupler delivers exceptional performance from 500 MHz up to 26.5 GHz. Featuring a precise 10 dB coupling factor, this compact coaxial component enables reliable signal sampling, power monitoring, and feedback loop management without disrupting the main transmission line.

Built with durable passivated aluminum housings and precision SMA-female connectors, this 50 Ω directional coupler ensures low insertion loss, high directivity, and minimal VSWR across an extremely broad frequency spectrum, making it an essential tool for modern microwave engineering and broadband ATE setups.

Key Features & Benefits

• Ultra-Wideband Frequency Range (0.5–26.5 GHz): Covers VHF, UHF, L, S, C, X, Ku, and K-band frequencies in a single, versatile component.
• Precise 10 dB Coupling Value: Delivers stable, repeatable signal sampling with minimal sensitivity variation across wide bandwidths.
• High Average Power Rating (30 Watts CW): Robust thermal design handles substantial forward power safely in high-frequency test environments.
• High Directivity & Low Insertion Loss: Maximizes signal isolation between forward and reverse paths while preserving primary signal strength.
• Low VSWR (≤ 1.60:1 typical): Minimizes internal reflections and signal distortion across the entire 26.5 GHz operating window.
• Precision SMA-Female Interfaces: Gold-plated center conductors and ruggedized connectors ensure long-term mechanical repeatability and low contact resistance.
