Embodiment Construction

[0019] In order to make it easier for those skilled in the art to understand the technical solution of this patent, and at the same time, in order to make the technical purpose, technical solution and beneficial effect of this patent clearer, and to fully support the protection scope of the claims, the following is a specific case in the form of this patent. The technical solution of the patent makes further and more detailed descriptions.

[0020] refer to figure 1 , The test system consists of normal temperature load, standard gain speaker, low noise amplifier, RF test cable, spectrum analyzer and rectangular waveguide components. The loss of rectangular waveguide components is calculated by measuring the output noise power of the system when the standard gain horn is placed at room temperature and pointing to the direction of the clear sky zenith without connecting and connecting the rectangular waveguide components.

[0021] In this embodiment, the rectangular waveguide c...

Abstract

The invention discloses a method for measuring the loss of rectangular waveguide components and belongs to the technical field of waveguide components. The present invention respectively measures the noise power of the standard gain horn pointing to the clear sky and the normal temperature load by measuring the standard gain horn pointing to the clear sky and the zenith direction under the conditions of not connecting the standard gain horn and connecting the rectangular waveguide components, respectively, by using a spectrum analyzer The measured noise power calculates the loss of the rectangular waveguide component. The method of the invention is simple and feasible, and has promotion and application value.

Description

technical field [0001] The invention relates to the technical field of waveguide components, in particular to a method for measuring loss of rectangular waveguide components. Background technique [0002] As we all know, rectangular waveguide components have the characteristics of large power capacity, small transmission loss, high reliability and strong anti-interference ability, and have been widely used in microwave communication systems, satellite communication systems and mobile communication systems. Rectangular waveguide components can realize the functions of directional transmission of microwave signals, radio frequency signal attenuation, isolation, filtering, polarization transformation and impedance matching. Commonly used rectangular waveguide components include waveguide phase shifters, attenuators, filters, directional couplers, duplexers, polarizers, power splitters, combiners and impedance converters, etc. [0003] Loss is a very important indicator of rect...
