Abstract
A system for matching impedances of a bare-die Integrated Circuit and bonding wires. A bare-die Integrated Circuit is configured to output or input, at an impedance of Z3, a millimeter-wave signal from three electrically conductive contacts. Three electrically conductive pads, printed on one of the laminas of a Printed Circuit Board (PCB) are connected to the three electrically conductive contacts via three bonding wires respectively, the bonding wires have a characteristic impedance of Z1, wherein Z1>Z3. One of the electrically conductive pads extends to form a transmission line signal trace of length L, the transmission line signal trace having a first width resulting in characteristic impedance of Z2, wherein Z2>Z3. The transmission line signal trace widens to a second width, higher than the first width, after the length of L, decreasing the characteristic impedance of the transmission line signal trace to substantially Z3 after the length L and onwards.
