Power combining module

Abstract

The invention relates to the technical fields of communication and radar, in particular to a power combining module which is used for a W-waveband transceiver assembly. The power combining module comprises an upper power amplifier module and a lower power amplifier module which are identical in structure and are arranged symmetrically, and an interlayer cavity which is arranged between the upper power amplifier module and the lower power amplifier module. The interlayer cavity comprises a waveguide structure. Each of the upper power amplifier module and the lower power amplifier module comprises a cavity, a power amplifier printed circuit board arranged in the cavity, and a radio-frequency link and insulators which are arranged on the front surface of the cavity. The power amplifier printed circuit board is vertically connected with the radio-frequency link through the insulators. All the devices in the power combining module disclosed by the invention are arranged in a three-dimensional structure, the devices in the radio-frequency link are vertically interconnected with the power amplifier printed circuit board through the insulators, the separation of a power supply from the devices is enhanced, electromagnetic compatibility of the module is improved, and the stability and the reliability of the power combining module are ensured. Different electronic devices are installed in different cavity layers, and the different electronic devices are vertically interconnected through the insulators. The devices on the same layer are arranged in a planar hybrid integration manner, and the miniaturization and integration of the power combining module are realized.

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...
