Parameter Test Method of Characteristic Impedances for High-Frequency Microwave PCB
This article puts forward a parameter test method to test characteristic impedance and differential impedance of the high-frequency microwave transmission line: for a section of transmission line, first testing its overall distributed inductance and distributed capacitance; for a section of coupling-line pair, first test each line’s self inductance, self capacitance, mutual inductance and mutual capacitance between two lines, and then calculating their characteristic impedance and differential impedance respectively by the equations. The key issues for applying this method are the choosing of the test frequency and the accurately measuring of the small inductance. The actual test results, which have been verified by the metallographic detection, show the method is very accurate.
