Abstract

The invention relates to the technical field of communication and radar, in particular to a W-band receiving and transmitting assembly. The W-band receiving and transmitting assembly comprises a local oscillator power splitter board, a transmitting chain, a receiving chain and a local oscillator chain. The W-band receiving and transmitting assembly further comprises a single-channel receiving module, a three-channel receiving module, an up-conversion module, a power synthesis module and a frequency multiplication module. All the modules are perpendicularly connected on the local oscillator power splitter board through waveguide interfaces. Due to the fact that all the modules are perpendicularly connected on the local oscillator power splitter board through the waveguide interfaces, the parasitic effect caused by packaging and interconnection is reduced. Due to the fact that all components in the functional module are arranged according to a three-dimensional structure and components in a radio frequency chain are perpendicularly connected with a power supply printing circuit board through insulators, isolation between a power supply and components is increased, and electromagnetic compatibility of the W-band receiving and transmitting assembly is improved. Meanwhile, different electronic components are installed in different cavity body layers, all components in the same layer are arranged in a planer hybrid integration mode, and miniaturization, integration and high reliability of the W-band receiving and transmitting assembly are achieved.

Description

technical field [0001] The invention relates to the technical fields of communication and radar, in particular to a W-band transceiver component. 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-band, under the same caliber ante...
