Problems solved by technology

However, when it is found that the characteristics of the finished RF coupler are not good, for example, when the coupling amount or directivity is insufficient, the circuit designer may need to redesign the circuit layout of the RF coupler and place the RF coupler with poor characteristics The coupler is scrapped, resulting in a waste of resources

Abstract

The invention provides an adjustable RF coupler and a manufacturing method thereof. The adjustable RF coupler comprises an insulating layer, a first transmission line and a second transmission line, wherein the second transmission line and the first transmission line are arranged correspondingly; the insulating layer is configured between the first transmission line and the second transmission line; the second transmission line comprises a plurality of line segments which are separated from one another and distributed along the extending path of the first transmission line; and at least one lead wire is used for electrically connecting at least two of the line segments, so that the at least two line segments are electrically conducted through the at least one lead wire. According to the adjustable RF coupler and the manufacturing method thereof, the number of scrapped adjustable RF coupler can be reduced.

Description

technical field [0001] The present invention provides a radio frequency (radio frequency, RF) coupler (coupler), and particularly relates to an adjustable radio frequency coupler and a manufacturing method of the adjustable radio frequency coupler. Background technique [0002] Due to the popularization of wireless communication products in recent years, the people's life has become more convenient and digitalized, and the market demand and manufacturing technology have been improving day by day, causing the design specifications of many circuits to change accordingly. Especially in the field of wireless communication, the design of receiving and transmitting end circuits has a great influence. [0003] In the design of a radio frequency front end module, a radio frequency coupler is usually designed for the back end circuit (for example, a power detector). In the design of the RF coupler, the circuit designer will do a proper simulation for its frequency band and coupling ...
