Description

technical field

[0001] The invention belongs to the technical field of microwave components, and in particular relates to the design of microwave components and test tooling, a microwave component test system and system construction, in particular to a dual-band distribution and combining device. Background technique

[0002] With the advancement and development of science and technology, digital components with advanced functions and stable performance have gradually replaced traditional solid-state components. It is an urgent problem to be solved to reduce the external connection ports of digital components and improve the reliability of components. Multi-channel microwave signals can use microwave combined transmission technology to reduce the external connection ports of digital components. This technology can save high-frequency cables in radar systems or communication systems and improve the stability of digital components.
