摘要： An amplifier GaAs MMIC for microwave band applications includes a ground electrode 8 having a via hole group 12 composed of three via holes 11 filled with plated metals 10a that are formed adjacently. The interaction thereby generates high frequency electromagnetic bonding, which reduces the ground inductance. According to the MMIC, the ground inductance of the via hole may be reduced while decrease of a strength and increase of a size being restrained.

摘要： Configuration of a connection between an even-harmonic mixer and a filter is simplified, thereby enabling size reduction. An even-harmonic mixer and a high-frequency bandpass filter are connected to each other via a transmission line, thereby forming a filter-integrated even-harmonic mixer. The length of the transmission line is set so that impedance on the transmission line side as viewed from a connection point between the even-harmonic mixer and the transmission line is approximately 0 for a frequency fLO of a local oscillation signal. This allows elimination of an open stub which is used in a conventional even-harmonic mixer and of which the line length to provide equivalent grounding for the frequency fLO is about 1 mm. Thus, the connection portion between the even-harmonic mixer and the high-frequency bandpass filter is simplified and a compact circuit layout for the filter-integrated even-harmonic mixer is obtainable.

摘要： Configuration of a connection between an even-harmonic mixer and a filter is simplified, thereby enabling size reduction. An even-harmonic mixer (21) and a high-frequency bandpass filter (23) are connected to each other via a transmission line (22), thereby forming a filter-integrated even-harmonic mixer. The length of the transmission line (22) is set so that impedance on the transmission line side as viewed from a connection point (24) between the even-harmonic mixer (21) and the transmission line (22) is approximately 0 for a frequency fLO of a local oscillation signal. This allows elimination of an open stub which is used in a conventional even-harmonic mixer and of which the line length to provide equivalent grounding for the frequency fLO is about 1 mm. Thus, the connection portion between the even-harmonic mixer and the high-frequency bandpass filter is simplified and a compact circuit layout for the filter-integrated even-harmonic mixer is obtainable.
