Coaxial fixed terminations absorb RFµwave energy and are commonly used as dummy loads of antenna and transmitter. They are also used as match ports in many multi-port microwave device such as circulator and directional coupler to make these ports which are not involved in the measurement be terminated in their characteristic impedance in order to ensure an accurate measurement. AF serial high power coaxial fixed termination's average power 2W**0KW, frequency range dc*6GHz, and feature wide frequency band, low VSWR, excellent capacity in anti-pulse and anti-burnout.
