Description
technical field [0001] The invention relates to the technical fields of communication and radar, in particular to a power synthesis module used in W-band transceiver components. Background technique [0002] According to frequency division, millimeter wave generally refers to electromagnetic waves with a wavelength between 1mm and 10mm. Compared with other wave bands, millimeter wave has a shorter wavelength and has a stronger ability to penetrate the ionosphere. It has a stronger ability to penetrate smoke, clouds and fog than infrared and visible light. It can work around the clock, and because of its relatively wide bandwidth, it can realize point-to-point high-capacity communication and high-resolution imaging. Among them, the W band is an important window frequency in the millimeter wave, and the research on the transceiver technology of this band is a hot topic in the millimeter wave application at present. Due to the higher frequency and shorter wavelength of the W-b...
