Coaxial Terminations

Coaxial terminations, also known as dummy loads, are devices designed to absorb all the power of a transmitted signal, preventing reflection back into the system. They are essential for protecting RF components and ensuring accurate measurements in testing environments, supporting a range of impedances and frequencies.

Dolph Microwave’s CL series of coaxial terminations are engineered to provide reliable and efficient power absorption for radio frequency and microwave systems. Serving as critical components for various applications, these terminations are designed not only to function as dummy loads for antennas and transmitter terminals but also to facilitate accurate impedance matching for multi-port microwave devices like circulators and directional couplers. With a focus on performance and durability, Dolph Microwave ensures these coaxial terminations meet the highest standards.
