SMA-JK M/F Fixed Coaxial Attenuator (DC to 4 GHz) Key benefits - Precise level control: Provides reliable fixed attenuation to reduce signal amplitude, protect sensitive receivers, prevent amplifier overload, and stabilize test measurements. - Wide frequency coverage: Operates from DC to 4 GHz so a single attenuator covers multiple RF bands and simplifies inventory. - High power handling: Rated for 10 W continuous power, enabling use with stronger signals without distortion or damage. - Low reflection, consistent performance: 50 Ω impedance design minimizes reflections and standing wave issues for more accurate measurements and cleaner signal chains. - Flexible options: Available in fixed attenuation values of 1, 3, 6, 10, 15, 20, and 30 dB to meet different signal conditioning needs. Features and compatibility - Model: SMA-JK M/F fixed coaxial attenuator. - Frequency range: DC to 4 GHz. - Power rating: 10 W. - Impedance: 50 Ω. - Attenuation choices: 1, 3, 6, 10, 15, 20, 30 dB. - Connector interface: SMA-JK M/F for direct use with SMA-compatible equipment. Typical applications - RF test and measurement: Insert into signal paths for repeatable attenuation during bench testing of receivers, amplifiers, and transceivers. - System protection and conditioning: Protect downstream components from high-power signals in transmitters, preselectors, or antenna feedlines. - Signal level matching: Use in lab setups or field deployments to match levels between instruments or subsystems and reduce reflections. Practical notes - Choose the attenuation value that keeps downstream devices within their safe input range while maintaining required signal-to-noise ratio. - Ensure proper SMA mating and torque to maintain impedance integrity. - Verify power and frequency limits for continuous operation to avoid overheating. This SMA-JK M/F fixed attenuator delivers straightforward, reliable attenuation across DC–4 GHz with multiple dB options and 10 W power handling for lab, field, and production RF applications.
