Frequency range - DC to 3 GHz or DC to 4 GHz (two standard versions available) Attenuation options and tolerance - Fixed attenuation values: 1, 2, 3, 5, 6, 10, 15, 20, 30, and 40 dB - Variable ranges with tolerance: - 1 to 10 dB: ±0.5 dB - 15 to 40 dB: ±1 dB Impedance and matching - Impedance: 50 ohms - Maximum VSWR: 1.2:1 Key benefits - Enables precise control of signal levels to protect receivers, test equipment, and to optimize dynamic range. - Flexible attenuation options cover a wide range of test and measurement needs with tight tolerances on common ranges. - Stable impedance and low VSWR minimize reflections for accurate readings and reliable performance in RF chains. Technical considerations - Designed for 50 ohm RF systems, suitable for bench testing, calibration, and integration into RF measurement setups. - Frequency coverage up to 3 GHz or 4 GHz depending on version, with a broad selection of attenuation steps to match application requirements. Use scenarios - RF lab calibration: attenuate high level signals to protect receivers during calibration and validation across DC to GHz ranges. - Transmitter and amplifier testing: set exact drive levels using fixed or adjustable attenuation to characterize performance without overloading downstream equipment. - Receiver protection in measurement setups: apply attenuation to prevent overload in sensitive front-end tests while preserving signal integrity with low VSWR. Notes - The specifications include both fixed attenuation values and specified adjustable ranges with tolerances. Ensure the correct version (3 GHz or 4 GHz) is selected for your application.
