Bird 100D RF Coaxial Load Resistor

The Bird 100D is a 100-watt, convection-cooled RF coaxial attenuator designed for applications requiring precise signal power reduction, impedance matching, and component isolation. It operates within a frequency range of DC to 3 GHz, offering reliable performance in demanding RF environments. This attenuator is constructed with robust, fully shielded materials to minimize stray radiation and prevent signal bleed, ensuring measurement integrity and protecting adjacent systems. Its self-cooling design requires no external power or moving parts, making it suitable for continuous use and low-maintenance operation. The Bird 100D is a bi-directional attenuator, meaning it can be used in either direction, providing flexibility in system integration.
