Coaxial Fixed Attenuators

Product Features

• Precise Attenuation Values: Provides accurately calibrated fixed attenuation levels (e.g., 1dB, 3dB, 6dB, 10dB, 20dB, 30dB, etc.), ensuring precise control of signal levels.
• Wide Frequency Range: Covers from DC (Direct Current) to high frequency bands (e.g., DC-67GHz), suitable for a broad spectrum of RF/microwave applications.
• Low Insertion Loss (beyond attenuation): Introduces minimal additional loss beyond its specified attenuation value, maintaining signal integrity.
• Excellent VSWR: Exhibits a very low Voltage Standing Wave Ratio across the entire operating frequency band, ensuring good impedance matching and reducing signal reflections.
• High Power Handling: Capable of processing RF signals at various power levels, from low-power testing to medium-power systems.
• Rugged and Durable: Features robust coaxial packaging and high-quality resistive materials, ensuring long-term stability and reliability.
• Temperature Stability: Attenuation values remain highly stable over a wide operating temperature range.
• Various Connector Types: Available with multiple standard coaxial connectors (e.g., SMA, N-type, 2.92mm, 2.4mm, etc.), facilitating easy integration with different equipment.
• Compact Design: Especially for low-power models, designs are typically very small and lightweight.

Applications

• Signal Level Control:
  • Reducing Signal Amplitude: Lowers excessively high signal levels to an acceptable range for receivers or test equipment, preventing saturation or damage.
  • Adjusting System Gain: Precisely tunes gain in RF links to optimize system performance.
• Impedance Matching:
  • Improving VSWR: Inserting an attenuator between mismatched components can effectively improve the apparent VSWR of the source and load, reducing reflections.
  • Isolation Effect: Provides a degree of isolation, reducing mutual interference between components.
• Extending Dynamic Range:
  • Used at the front end of test equipment like spectrum analyzers or power meters to prevent input overload, thereby extending their measurable dynamic range.
• Protecting Sensitive Equipment:
  • Prevents high-power signals from directly entering sensitive RF front-ends or test ports, avoiding damage.
• Signal Path Calibration:
  • Used to introduce a precise, known loss when calibrating RF test systems or links.
• Test and Measurement:
  • In laboratories and production lines, used to attenuate signals, simulate link loss, or provide fixed reference levels.
• Communication Systems:
  • In scenarios such as base stations, repeaters, and antenna feeders, used to balance signal levels and ensure signal quality.
• R&D Prototyping:
  • Serves as a flexible tool to adjust signal levels during the design and testing of new RF circuits.
