Durable, compact terminations for mid-power RF applications
25 Watt RF Load Series
Designed for bench testing, system protection, and reliable signal termination, Bird’s 25 Watt RF loads deliver low VSWR, stable performance, and rugged durability.
Explore the 25 Watt Series Loads
DC to 4 GHz | Convection-Cooled Loads
25-T Series
A reliable, general-purpose termination for everyday RF testing, transmitter loading, and port isolation. The 25-T Series offers rugged durability in a compact form, with connector flexibility to support a wide range of system setups.
DC to 6 GHz | Convection-Cooled Loads
25-6T Series
Designed for low-profile installations where space is limited, the 25-6T Series combines ultra-compact construction with excellent thermal handling. Ideal for lab environments, tight enclosures, and portable RF kits.
DC to 18 GHz | Convection-Cooled Loads
25-18T Series
Optimized for higher-frequency applications the 25-18T Series delivers low VSWR and stable impedance across broad bandwidths. Perfect for test benches, instrumentation setups, and systems requiring precise high-frequency termination.
Trusted in Industry Applications
Most Bird Analyzer Kits for the SiteHawk cable & antenna analyzer and SignalHawk spectrum analyzer include a 25-T-MN load. This allows terminated power measurements to be made with an included RF power senor, and allows accurate measurements of cables by terminating the non-measurement end.
Why RF Pros Choose Bird Loads
Accuracy, protection, and lasting performance—Bird loads deliver where it counts. From convection to water- and air-cooled designs, each is built to absorb full RF power, minimize VSWR, and perform reliably in the toughest environments.
