Description

technical field [0001] The invention relates to a circuit layout technology, in particular to a circuit layout structure of capacitance compensation type differential mode wire. Background technique [0002] Due to the rapid development and wide demand of wireless communication technologies such as wireless networks, mobile phones and Global Positioning System (GPS), the design and manufacture of microwave circuits has become a very popular electronic technology in the electronic industry. Basically, a conductive circuit called microstrips is arranged on a circuit board dedicated to microwave circuits, so that the microstrips transmit ultra-high frequency microwave signals, such as 1 GHz to 3 GHz (gigahertz) microwave signals. [0003] In the design of microwave circuits, it is often necessary to use a paired differential mode wire to transmit two paired microwave signals. FIG. 1 shows a conventional differential mode wire circuit layout structure 100 . As shown in the fig...
