A debugging device for matching debugging of radio frequency circuits

Abstract

The invention discloses a debugging device for matching and debugging radio frequency circuits. The debugging device comprises a substrate and an adjustment module; the adjustment module is electrically connected with a transmission line of a to-be-debugged radio frequency circuit; the adjustment module comprises a conductor band arranged on the substrate; and a sliding contact part electrically connected with the conductor band and configured to: form short circuit via a part of the conductor band and access the rest part of the conductor band to the radio frequency circuit when sliding along the length direction of the conductor band. In a debugging process, the sliding contact part is adjusted, so that the effective part of the microstrip transmission line of the radio frequency circuit changes continuously, accordingly the matching is optimal, and the debugging objective is achieved. When the debugging device is used for matching and debugging the radio frequency circuit, the elements do not need to be changed or welded again, nor a debugging circuit board needs to be manufactured again, thereby reducing ineffective iterative processes in the debugging process and improving the overall debugging efficiency.

Description

technical field [0001] The invention belongs to the technical field of radio frequency circuit debugging, in particular to a debugging device for matching debugging of radio frequency circuits. Background technique [0002] The development of wireless communication technology is changing with each passing day. Among them, the design of radio frequency circuit is the core component of the development of wireless communication equipment. In the process of RF circuit design and development, the matching and debugging of RF circuits is a very important link. [0003] When matching and debugging, there are generally two existing debugging methods: one is to use separate components, such as inductors or capacitors, to build a matching network. In the debugging process, it is necessary to replace components with different nominal values ​​or change the position of the components many times to achieve the purpose of debugging and optimize the matching. In this method, the componen...

Problems solved by technology

This method cannot adapt to the highly integrated requirements of the current circuit design, and in the process of debugging, the microstrip branches also need to be made iteratively for many times, which still affects the efficiency of debugging
