More Information
Summary:A radio frequency circuit with font routing to replace a resistor includes a routing layer and a ground layer. The routing layer includes a first pad, a second pad and a font routing unit. The second pad is corresponding to the first pad. The font routing unit is connected between the first pad and the second pad, and has a trace width. The trace width is less than a 50 ohm trace width. The ground layer is disposed below the routing layer and is separated from the routing layer by a height. The font routing unit has a second equivalent impedance at the radio frequency, the second equivalent impedance is determined according to the trace width, the height and the radio frequency, and the second equivalent impedance is the same or similar to a first equivalent impedance.
