An x-band multi-polarization multi-channel microwave component

Abstract

The present application provides an X-band multi-polarized multi-channel microwave component, the multi-polarized multi-channel microwave component includes: a common waveguide, an X1 channel, an X2 channel, and an X3 channel, and the X1 channel and the X3 channel are polarized The form is the same, the X2 channel is orthogonal to the X1 channel and the X3 channel respectively; after the electromagnetic waves of different frequencies are input through the X1 channel, X2 channel and X3 channel, they are output or radiated through the common waveguide, Simultaneous operation of multiple frequencies is realized; the X1 channel is in the +Y direction, and the X2 channel is in the +X direction. The invention realizes multi-channel and multi-polarization microwave components by utilizing the combination form of polarization isolation and frequency selection components, reduces selection of frequency selection components, and realizes compact design.

Description

technical field [0001] The invention relates to the field of microwave components for transmitting X-band radio waves for deep-space probes, in particular to an X-band multi-polarization and multi-channel microwave component. Background technique [0002] At present, the known general multi-channel components use frequency selection devices to share multiple channels and multiple frequencies. The selection of multiple frequency selection devices leads to large size and complex layout of the multi-channel components. [0003] In the known multi-channel component using polarization, generally only two channels are shared, and it is difficult to realize the sharing of multiple channels. [0004] In deep space exploration, due to the limitation of the size of the spacecraft structure, it is required to share more than three channels in a small size, and at the same time, the isolation between the three channels is higher than 50dB. The above-mentioned known multi-channel compone...

[0002] At present, the known general multi-channel components use frequency selection devices to share multiple channels and multiple frequencies. The selection of multiple frequency selection devices leads to large size and complex layout of multi-channel components.

[0003] The well-known multi-channel components that use polarization are generally shared by only two channels, and it is difficult to share multiple channels.

[0004] In deep space exploration, due to the limitation of the size of the spacecraft structure, it is required to realize the sharing of more than three channels in a small size, and at the same time, the isolation between the three channels is higher than 50dB. The above-mentioned known multi-channel components cannot meet the index requirements.
