This invention relates to a phased array antenna subarray, comprising an external interface layer, a beamforming network layer, an amplitude and phase multifunction layer, a low-noise amplifier (LNOA) layer, and an antenna layer. The antenna layer and the LNOA layer are disposed on a first metal-based PCB board, while the amplitude and phase multifunction layer, the LNOA layer, and the antenna layer are disposed on a second metal-based PCB board. The bottom layer of the first metal-based PCB board and the top layer of the second metal-based PCB board are connected together, achieving integrated encapsulation of the external interface layer, beamforming network layer, amplitude and phase multifunction layer, LNOA layer, and antenna layer. Both the first and second metal-based PCB boards are provided with multiple grounding and heat-conducting vias. This invention enables the phased array antenna to be lightweight, small, and thin while also possessing excellent heat dissipation and good scalability, allowing for expansion of the number of elements and frequency bands.

The application discloses a double-station blow dryer testing machine, which comprises a rack and at least two groups of testing stations. Each testing station comprises a feeding area and a first testing area above the end face of the rack and a second testing area below the end face of the rack. A detection opening is arranged in the first testing area. The feeding mechanism comprises a first moving module and a positioning jig installed on the moving end of the first moving module. The positioning jig is provided with a power supply interface. A second moving module is movably arranged in the second testing area. A visual detection module, a wind speed detection module, a negative ion detection module and a water ion detection module are installed on the moving end of the second moving module. The voltage resistance testing mechanism comprises a first voltage resistance testing component and a second voltage resistance testing component. The application has the advantages of high testing efficiency, space saving, multifunctional integration, strong universality and the like, and can be compatible with various blow dryers with different shapes, gear switches and testing requirements.
