Four sections of coupled line structure sizes are almost the same, and four sections of coupling lines are respectively three line coupling line of first segment, second segment three Line coupling line, three line coupling line of third section and the 4th section of three line coupling line;The first port and input of three line coupling line of first segment End is connected, and the third port of three line coupling line of first segment is connected with the second port of three line coupling line of second segment, three line of first segment 4th port end of coupling line is connected with the first port end of three line coupling line of second segment, the second end of three line coupling line of first segment Mouth end is connect with the third port end of the 4th section of three line coupling line;The isolation end of coupler and the third of three line coupling line of second segment Port connection, the 4th port of three line coupling line of second segment is connected with the second port of three line coupling line of third section;Third section three The first port of line coupling line is connected with coupled end, the 4th port of three line coupling line of third section and the 4th section of three line coupling line First port is connected, and the third port end of three line coupling line of third section is connected with the second port end of the 4th section of three line coupling line; 4th section of three line coupling line third port end is connected with the straight-through end of coupler.
Wherein the specific design procedure of the size of coupler design is as follows:
Step 1: the thick metal layers for selecting technique to provide reduce signal wire loss, coupling as the signal wire metal layer of coupler The quatrter-wavelength line that the original dimension of device is set as under required working frequency is long, i.e. total metal at input terminal to straight-through end is long Degree is set as the quarter-wave length of working frequency.Electromagnetic-field simulation result is carried out to it calculates four port property of coupler Can, including isolation, straight-through end and coupled end signal conformance, each port standing wave.The working frequency of coupler is relatively low at this time.
Step 2: by adjusting three line coupling lines width and spacing adjustment coupler four port performances to compared with the figure of merit, press The working frequency Yu target operating frequency of coupler carry out ratio calculation at this time, by coupler input to the total length at straight-through end It reduces in proportion, repeats step 2 until the center operating frequency of coupler reaches target operating frequency.The working frequency of coupler It is a tradeoff with its bandwidth of operation, the size of coupler can be further decreased by reducing the requirement of bandwidth of operation.
