Leader-mw Introduction 500W power attenuator

Leader-mw  2.92mm connector, 5W power-rated attenuator operating up to 40GHz is a precision radio frequency (RF) component designed for demanding microwave applications. Its primary function is to reduce signal power by a specific, controlled amount (e.g., 3dB, 10dB, 20dB) while maintaining signal integrity.

The key to its performance lies in its specifications. The 2.92mm (K-type) connector is crucial, as it ensures reliable operation up to 40GHz, making it compatible with systems and cables used in millimeter-wave testing, aerospace, and 5G R&D. The 5-watt power handling rating indicates its robustness, allowing it to withstand higher signal levels without damage or performance degradation, which is vital in transmitter testing or high-power amplifier chains.

This class of attenuator is engineered for minimal insertion loss and a flat frequency response, meaning the attenuation level remains consistent across the entire DC to 40GHz band. This precision is essential for accurate measurements in test and measurement setups, ensuring that signal levels are correctly set for sensitive equipment like vector network analyzers and spectrum analyzers. In essence, it is an indispensable tool for controlling signal strength with high accuracy in advanced high-frequency systems.
