Problems solved by technology

However, the currently commonly used high-frequency broadband synthesis technology usually adopts a planar microstrip transmission line structure. As the frequency increases, the size and loss of the planar microstrip transmission line become larger and larger, especially in the millimeter-wave frequency band, which is difficult to meet the miniaturization and high-speed requirements. efficiency requirements
