Abstract: To extract the microwave transition characters of a multilayer printed circuit, a method was proposed; the circuit was designed by establishing the mathematical relationship of each channel, then process the test data to get the microwave transition characters. Finally, we used this method to extract the microwave transition characters of a multilayer printed circuit，including the vertical transit loss , the horizontal transit loss , the right-angle transit loss and the loss of a unit transmission line. The results can provide a reference for the design of microwave circuit using the stack.
