Fiplex Coupler Splitter Combiner Tapper & Attenuators

  • Directional Couplers
    Devices that split RF power asymmetrically between ports with precise coupling values (e.g., 6, 10, 15, 20, 30 dB). They offer low insertion loss and excellent VSWR.
  • 3 dB Hybrid Coupler
    Splits or combines signals evenly (3 dB each way) for balanced RF distribution across wide frequency ranges.
  • Dual‑Band Combiner
    Combines two distinct RF bands into one output, enabling multi-band system integration.
  • Multiband Combiner
    Aggregates multiple bands (e.g., VHF, UHF, 700/800 MHz) into a single output for broad-spectrum coverage.
  • Broadband Power Splitters
    Divide input power into 2, 3, or 4 outputs for efficient signal distribution.
  • High‑Power Tappers
    Tap off a fixed percentage of input power (e.g., 3%, 6%, etc.) while passing the remainder.
  • Coaxial Fixed Attenuators
    Provide fixed attenuation (e.g., 5, 10, 15, 20, 30 dB) to manage signal levels.
  • RF Loads
    Terminate unused RF paths with matched 50 Ω loads to prevent reflections.

Key Features

  • Wideband frequency coverage (70 MHz to 2700 MHz or higher)
  • Low insertion loss and high isolation (VSWR <1.3)
  • High power handling (up to 300 W continuous)
  • PIM compliance for critical telecom and public-safety systems
  • Accurate coupling values (±0.8 dB typical)
  • Rugged, weather-resistant construction
  • Multiple connector options (N, DIN, 4.3/10)
  • Long MTBF for reliability

Applications

  • Distributed Antenna Systems (DAS) for in-building coverage
  • Bi-Directional Amplifier (BDA) systems for public safety
  • Telecom networks (LTE, P25, TETRA)
  • Signal testing and monitoring
  • Coverage extension projects
  • RF isolation and termination in complex networks
