Millimeter wave high-reliability waveguide module for preventing leakage of radiofrequency signals

Abstract

The invention discloses a millimeter wave high-reliability waveguide module for preventing leakage of radiofrequency signals. The millimeter wave high-reliability waveguide module comprises an upper housing, a lower housing, an installing cavity and a waveguide cavity. The upper housing and the lower housing are cube structures and are buckled together. The installing cavity for installing a radiofrequency chip and the waveguide cavity for transmitting millimeter wave signals are embedded in the contact surfaces of the upper housing and the lower housing. The upper housing and the lower housing are fixed by positioning pins and fastening screws. The installing cavity for installing the radiofrequency chip and the waveguide cavity for transmitting the millimeter wave signals are embedded in the contact surfaces of the upper housing and the lower housing so as to enhance the cooperation between the radiofrequency chip and an active circuit and solve poor stability of a conventional waveguide module. By reasonably arranging the positioning pins and the fastening screws, the leakage of the millimeter wave signals is eliminated to the utmost extent and a detect of low reliability of the conventional waveguide module is compensated.

Description

technical field [0001] The invention relates to a millimeter-wave high-reliability waveguide module for preventing radio frequency signal leakage, which is especially suitable for a millimeter-wave waveguide structure and belongs to the field of microwave technology. Background technique [0002] Conventional microwave RF modules usually adopt a coaxial structure, but as the operating frequency increases, the coaxial structure will degrade the RF performance of the product in the millimeter wave or even higher frequency bands. In order to ensure good RF performance, a waveguide structure is usually used instead Coaxial structure, low transmission loss of waveguide structure, small port return loss. Because there are active modules in this structure, circuit chips and radio frequency chips need to be installed inside the waveguide cavity, so the waveguide module cannot be processed in an integrated manner, and usually adopts the form of a two-body or multi-body structure, suc...
