Abstract

The present invention discloses a novel waveguide attenuator, and is characterized in that: the novel waveguide attenuator includes three mutually parallel rectangular waveguides, and broadsides of adjacent waveguides are coupled through a plurality of coupling holes; the waveguide attenuator has an output port which is one end of the rectangular waveguide on the outside and has an input port which is one end of the rectangular waveguide in the middle; and other ends of the three rectangular waveguides are provided with absorption loads. The model structure of the novel waveguide attenuator provided by the invention employs the connection of three intercoupling rectangular waveguides and enables the response curve of the structure to be in complementary response to a Bi-chebyshev method, thereby fundamentally solving the problem of flatness of the ultra wide band waveguide attenuator, doubling the capacity of power, having a better echo performance, and decreasing the design length of the waveguide attenuator.

Description

technical field

[0001] The invention belongs to the field of electronic communication, in particular to an ultra-broadband waveguide attenuator. Background technique

[0002] In the field of electronic communication and radar testing, it is often necessary to use broadband waveguide attenuators to test the performance of the system. The test attenuator requires accurate attenuation value, good echo, ability to withstand large power, and wide operating bandwidth.

[0003] Although the commonly used coaxial attenuators have a wide bandwidth, they often cannot meet the requirements due to interface problems, power capacity, echo and other issues. The waveguide attenuator has the characteristics of large power capacity, good echo performance, direct connection with the standard waveguide port, durable skin, and becomes the first choice for testing. The broadside coupling structure used in the commonly used waveguide attenuators at present has a response curve of Chebyshev curv...
