RF Couplers and Bias Tees play key roles in RF systems — couplers help tap or divide RF power without disturbing the main signal flow, while bias tees inject DC power into RF lines for powering active components such as LNAs and antennas without affecting RF performance.

🔸 Advantages:

  • Enable non-intrusive signal sampling and monitoring

  • Combine DC + RF onto a single coaxial line using bias tees

  • Improve RF system modularity and reduce cable clutter

  • Wide frequency support with low insertion loss

  • Essential for amplifiers, test benches, active antennas, and signal conditioning

🔸 Working Principle:

  • Directional Couplers tap a portion of the signal from the main line (usually -6 to -30 dB) while maintaining signal integrity.

  • Bias Tees use internal capacitors and inductors to separate or combine RF and DC signals: the inductor passes DC while blocking RF, and the capacitor passes RF while blocking DC.

🔸 Applications:

  • RF signal monitoring and power detection

  • Test & measurement setups

  • Biasing of LNAs, mixers, and antennas

  • Satellite and wireless communication systems

  • Laboratory prototyping and research

🔸 Key Strengths:

  • High isolation between ports in couplers

  • Minimal signal distortion and low return loss

  • Wide dynamic range

  • Compact and rugged enclosures

  • Compatible with SMA, N-Type, and 2.92mm connectors
