Adjustable open cirecuit guide plate circuit

Abstract

A adjustable open stud circuit contains at least a conductive metal piece and a conductive connective assembly having equal width with the open end of said open stud, wherein the conductive metal piece can be divided into plurality of metal pieces which can be interval distributed and increased for forming a matrix form. Said invention can be soldered with a preset metal having equal width for adjusting the total length of the end of the open stud circuit.

Description

technical field [0001] The present invention relates to an open stud circuit (open stud circuit), especially an adjustable open stud circuit (tunable open stud circuit), which solders (solding) at least one preset with the same width as the open end of the open stud circuit Conducting a metal pad to extend the length of the open guide plate to the end of the metal plate, thereby achieving the purpose of adjusting the total length of the open end of the open guide plate. Background technique [0002] In areas dealing with radio frequency (RF) and microwave (microwave) applications, figure 1 The Smith chart in is often used to determine impedance-related issues, for example, to determine different impedance matching requirements between interconnected blocks and to determine unknown impedance values. Such as figure 1 As shown, it uses a small area mapping method (conformal mapping) to map all possible orthogonal passive impedances on a polar diagram with complex reflection c...

Problems solved by technology

However, since the open guide plate is directly formed on the printed circuit, once the plate making is completed, the length of the open guide plate on it is fixed and is not easy to change.

In this way, the related debugging (debugging) work (adjusting the impedance value) will become quite difficult
