Description

Technical Field

[0001] This utility model belongs to the field of polarization switching technology, specifically a combined two-input two-output polarization switching switch structure. Background Technology

[0002] Microwave product modules, as components of microwave systems, are widely used in fields such as communication and detection. Based on function, they generally include amplification, switching, power splitting and combining, filtering, and frequency conversion. As a crucial part of microwave module products, structural components primarily house microwave devices, providing shielding and heat dissipation, thus helping the microwave module achieve its specific microwave performance.

[0003] A polarization switch is a device used to control the polarization state of electromagnetic waves. Its main function is to quickly switch between different polarization modes (such as linear, circular, and elliptical polarization) or select a specific polarization mode. Because microwave products typically require lightweight and small size in their operating environments, their structural design usually demands a compact structure. However, due to the overlapping issues in the RF links of polarization switching products, typical designs involve complex links and too many intermediate transitions, resulting in both complex product structure and excessive size and weight; it also leads to excessive insertion loss, affecting product performance.
