DESCRIPTION
The Bird 150 Series consists of high-power fixed RF attenuators rated at 150 watts, designed for use in demanding RF measurement, broadcast, and system integration environments. All models are precision 50 ohm devices engineered to provide stable attenuation, low VSWR, and reliable thermal performance across their specified frequency ranges.
The 150-A Series represents Bird’s standard bidirectional attenuator design for general-purpose RF applications. The 150-SA Series incorporates additional safety features suitable for higher-risk environments and controlled installations. The 150-WA Series is a uni-directional attenuator family intended for directional RF paths where reflected power must be managed.
All series are available in standard attenuation values from 10 dB up to 40 dB, using Bird’s established MFN (N male to N female) and FFN (N female to N female) connector configurations. Models are manufacturer-defined and listed strictly according to Bird’s published series structures.
