Abstract

The invention belongs to the microwave technical field, in particular to a method for guaranteeing port standing wave performance. The method comprises the following steps: 1, enlarging the diameter of a non-positioning section and ensuring that the diameter of the non-positioning section is smaller than the diameter of a tin storage section; 2, arranging a solder sheet between a substrate and a structural member, wherein a solder hole is arranged in the solder sheet to expose an air section; 3, heating the solder sheet to melt to realize the weld of the substrate and the structural member; 4,coating the inner surfaces of the positioning section and the tin storage section of the structural member with a solder layer; 5, placing a coaxial connector in the structural dmember, heating the solder layer to melt, and realizing welding of the coaxial connector and the structural member. By optimizing the design of structural member and welding process, the port standing wave performance canbe effectively guaranteed.

Description

technical field

[0001] The invention belongs to the field of microwave technology, and in particular relates to a method for ensuring the standing wave performance of a port. Background technique

[0002] Most of the external microwave signal input and output ports of the microwave module are coaxial connectors, while the internal microwave signal input and output ports of the microwave module are mostly microstrip line structures set on the substrate, and the metal probes of the coaxial connector are transitionally connected to the microstrip line When , there is a certain discontinuity, which will affect the port standing wave. In order to eliminate the influence of the discontinuity of the transition connection on the standing wave of the port, the impedance matching design of the port is required. One of the commonly used methods for impedance matching design is to design air sections of different lengths and diameters on the structural parts according to the signals of ...
