The electromagnetic coupling between input and output microstrip lines inside the microwave amplifier module is a serious problem. For the suppression of the coupling, putting a lossy composite sheet beneath the upper cover is effective. By the coupling formula between two microstrip lines in the microwave amplifier module which we have reported, we optimized the thickness materials and filler contents of three types of lossy composite sheets, i.e. carbon rubber, soft ferrite rubber and soft magnetic metal rub- ber, in an amplifier module. We theoretically and experimentally found that the soft magnetic metal composite sheet is most effective for the suppression of coupling between two microstrip lines.
