Description

Technical Field

[0001] The utility model relates to the technical field of high-power attenuators, and particularly relates to a miniaturized structure of a high-power attenuator. Background Art

[0002] An attenuator is an electronic component that provides attenuation and is widely used in electronic devices. Its main uses are: (1) adjusting the magnitude of signals in a circuit; (2) in a comparative measurement circuit, it can be used to directly read the attenuation value of the measured network; (3) improving impedance matching. If some circuits require a relatively stable load impedance, an attenuator can be inserted between this circuit and the actual load impedance to buffer the change in impedance. For the design of high-power attenuators, generally, multiple attenuation chips are used to form an attenuation chip group to achieve high-power attenuation step by step. However, with the increase in the number of attenuation chips, the length of the carrier of the attenuation chips, that is, the attenuator cavity, will become longer, thus restricting the installation and use of the attenuator.
