Embodiment approach 2

[0101] Embodiment 2: the area of ​​the first metal sheet included in the first reactance device, and the area of ​​the second metal sheet included in the second reactance device are both smaller than the first area (the preferred value can be 100 square millimeters) and greater than the second area. In the case of an area (a preferred value may be 1 square millimeter), the fifth value is greater than or equal to the first value, and the sixth value is less than the first value and greater than the second value. That is to say, switching between the cross transmission state and the coupling transmission state of the reconfigurable cross coupler can be realized.

Abstract

A reconfigurable cross coupler is provided, including: N-level branch lines, four ports, a first reactance device and a second reactance device, and the N-level branch lines are composed of N-level quadrilateral microstrip branch lines cascaded , N is an integer greater than or equal to 3, wherein the four corners of the branch lines connected in N stages are respectively connected to four ports through impedance matching lines; the four ports include an input port, an isolated port, a cross output port, and a through output port. The middle position of the first side of the N-level connected branch line loads the first reactance device; the middle position of the second side of the N-level connected rectangular branch line loads the second reactance device; the first reactance device and the second reactance device The reactance value is variable, and is used to adjust the signal output state of the cross output port and the through output port. By adopting the present application, the switching of the signal transmission path in the reconfigurable cross coupler can be realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a reconfigurable cross coupler. Background technique [0002] With the development of modern communication technology, microwave and millimeter-wave circuits as radio frequency front-ends have been widely used, and their functions have become more and more, and the complexity of the circuits has become higher and higher, which makes the cross-coupler Become a commonly used device at the intersection of circuits. A traditional cross-coupler is composed of two layers of metal wires that are not in contact with each other. This structure increases the complexity of the circuit and requires special processing techniques, such as a jumper process. This increases processing costs and is difficult to integrate with other circuits. With the continuous improvement of PCB technology, microwave circuits are also rapidly developing towards planarization, so planarized cross couplers...
