Miniaturized orthogonal LTCC coupler adopting new topological structure

Abstract

The invention discloses a miniaturized orthogonal LTCC coupler adopting a new topological structure. The coupler is formed by the new topological structure, the topological structure consists of a capacitor C1, a capacitor C2, a capacitor C3, an inductor L1, an inductor L2, an inductor L3 and an inductor L4, meanwhile, the topological structure is provided with four ports: a port 1, a port 2, a port 3 and a port 4, the capacitor C1 is arranged between the port 1 and the port 2, the capacitor C3 is set between the port 3 and the port 4, one end of the inductor L1 is connected with the inductorL3, and the connection site thereof is connected with one end of the capacitor C2, the other end of the inductor L1 is connected with the port 1, the other end of the inductor L3 is connected with theport 3; one end of the inductor L2 is connected with the inductor L4, and the connection site thereof is connected with the other end of the capacitor C2, the other end of the inductor L2 is connected with the port 2, and the other end of the inductor L4 is connected with the port 4. The miniaturized orthogonal LTCC coupler realizes the miniaturization of the coupler while effectively widening the bandwidth of the coupler, and has high performance and high reliability, low cost, and adaptability to various environments.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a miniaturized orthogonal LTCC coupler adopting a new topology. Background technique [0002] The coupler is a radio frequency device that extracts a small part of the signal from the main channel of the wireless signal. The coupler can have a variety of lumped parameters. Among them, the coupler with the traditional lumped parameter parameter of 3dB generally uses a quarter-wavelength transmission line. However, when the coupler works at a low frequency, the quarter-wavelength transmission line is too long and the occupied area is too large. The topological structure in some couplers cannot realize large broadband applications, and the inductive and capacitive components in the topological structure of some couplers Too many, making the resulting coupler too bulky. Contents of the invention [0003] The purpose of the present invention is to provide a kind of miniaturization...
