Designed for wideband applications from 0 to 6 GHz, this high-performance RF fixed attenuator delivers a precise 40 dB attenuation with a standard 50Ω impedance. It features outstanding high-power handling, supporting up to 50 W average input power at 25℃. Integrated with an aluminum alloy heat sink, it ensures exceptional thermal stability and an ultra-low temperature coefficient (<0.0004 dB/℃) across an extreme operating temperature range of -55℃ to +125℃. With a maximum VSWR of 1.25:1, it guarantees excellent signal matching and transmission quality. It utilizes a gold-plated brass inner conductor, a passivated outer conductor, and a PTFE insulator, achieving an insulation resistance of ≥5000 MΩ.
