Problems solved by technology

[0003] like figure 1 and figure 2 As shown, in the traditional RF coupler, the coupling lines C1 and C2 are designed in a straight line. The RF signal is input through one end of C1, and through the electromagnetic field coupling of C1 and C2, part of the energy is transferred to C2. The consistency and anti-interference ability of the coupler needs to be improved

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a novel radio frequency coupler and a device, related to the technical field of circuit design and devices. The novel radio frequency coupler comprises a first coupling line, asecond coupling line and an dielectric medium, the dielectric medium is arranged between the first coupling line and the second coupling line, the first coupling line is set to be a linear structure,the second coupling line is set to be a nonlinear structure, thus, coupling length is increased; on a design of the conventional radio frequency coupler, by changing one of the coupling lines to be an inclined line or a ladder type routing, thus, the coupling length is increased, meanwhile, resistance of coupler parameters to variation of technologies is increased, and consistency and anti-interference ability of the coupler are improved.

Description

technical field [0001] The invention relates to the field of circuit design and device technology, in particular to a novel radio frequency coupler and device. Background technique [0002] RF couplers are widely used in modern RF systems, including but not limited to wireless communication systems such as 2 / 3 / 4 / 5G and WiFi / Zigbee / Bluetooth. The performance parameters of the coupler have a great influence on other components that depend on its coupling effect, and the requirements for the consistency of its coupling performance are getting higher and higher, which plays an important role in the indicators of the entire wireless system. [0003] Such as figure 1 and figure 2 As shown, in the traditional RF coupler, the coupling lines C1 and C2 are designed in a straight line. The RF signal is input through one end of C1, and through the electromagnetic field coupling of C1 and C2, part of the energy is transferred to C2. The consistency and anti-interference ability of the...
