Abstract

The invention discloses a high-power coupled step attenuator. The attenuator comprises a coupled constant value attenuator and a digital step attenuator, wherein the coupled constant value attenuatorand the digital step attenuator are assembled together to form the high-power coupled step attenuator. According to the high-power coupled step attenuator, the coupled constant value attenuator and the digital step attenuator are combined, coupled constant value attenuation devices are added at two transmission ports of the digital step attenuator, and during the transmission, the power is attenuated by the coupled attenuation devices at two ends, so that the step attenuator can be applied in high-power scenes to realize the high-power coupled step attenuator. The average power borne by the high-power coupled step attenuator is improved to 50W, so that the problem that the present digital step attenuators cannot bear high power is solved; and the high-power coupled step attenuator is simple in structure, easy to process and convenient to produce in the aspect of structural design.

Description

technical field [0001] The invention relates to an attenuator, in particular to a high-power coupled step attenuator, which belongs to the technical field of communication. Background technique [0002] Attenuators are widely used in microwave communication systems such as measuring systems, improving impedance matching, and adjusting circuit signal sizes. At present, digital step attenuators can only withstand low power (about 1W), which cannot meet the requirements of high power tolerance. A step attenuator capable of carrying high power is urgently needed. Contents of the invention [0003] The present invention aims at the deficiencies of the prior art, and proposes a high-power coupled step attenuator. [0004] In order to solve the above problems, the technical scheme adopted in the present invention is as follows: [0005] A high-power coupled step attenuator is characterized in that the attenuator includes a coupled fixed value attenuator and a digital step atten...
