One kind of high-power coaxial fixed attenuator

The present invention discloses a high power coaxial fixed attenuators, mainly by the SMA female connector, an SMA male connector and the attenuator consisting of a cavity; said cavity by a radiator, two of the housing, two core cavity, two attenuation sheet, grounding clip, piece composition; male joint comprises a threaded sleeve, the collar, the male housing, insulators, male inner conductor, a spring, contacts the cap; female connector comprising a female housing, the female conductor, insulator, a spring contact as a cap; even piece body comprising a conductor piece shell, the insulator, the spring, the contact cap. The present invention utilizes novel metal oxide as the substrate resistance and advanced technology, so that a high power density, stable resistance value. Through the card-type attenuator design optimization, to achieve a small VSWR, bandwidth requirements. Product operating band from DC to 26.5GHz, the power capacity of 50W, has good rapid heat dissipation capability, anti-burning ability, good mechanical stability, good repeatability.
