Abstract

The invention provides an adjustable radio frequency coupler and a manufacturing method thereof. The adjustable radio frequency coupler includes an insulating layer, a first transmission line and a second transmission line. The second transmission line is arranged corresponding to the first transmission line, and the insulating layer is arranged between the first transmission line and the second transmission line. The second transmission line includes a plurality of line segments separated from each other and arranged along the extension path of the first transmission line, wherein at least one wire is used to electrically connect at least two line segments, so that the at least two line segments are electrically conductive via at least one wire Pass. The invention can reduce the number of scrapped adjustable radio frequency couplers.

Description

Technical field [0001] The present invention provides a radio frequency (RF) coupler, and particularly relates to an adjustable radio frequency coupler and a manufacturing method of the adjustable radio frequency coupler. Background technique [0002] As the popularization of wireless communication products in recent years has promoted the convenience and digitization of people's lives, market demand and the increasing progress of manufacturing technology have caused many circuit design specifications to change accordingly. Especially in the field of wireless communications, the design of the receiving and transmitting end circuits has a significant impact. [0003] In the design of the front end module of the radio frequency, the radio frequency coupler is usually designed for the back end circuit (for example, a power detector) to perform. In the design of the RF coupler, the circuit designer will perform the circuit layout (layout) after making appropriate simulations for its f...
