Abstract:
1. A high-frequency device having high-frequency-signal-treating circuits in and on a laminate substrate comprising pluralities of rectangular dielectric layers having conductor patterns, said high-frequency-signal-treating circuits having amplifier circuits and switch circuits; terminals including input and output terminals of high-frequency signals, power supply terminals of said amplifier circuits and power supply terminals of said switch circuits being formed on one main surface of said laminate substrate; power supply lines each having one end connected to each of the power supply terminals of said amplifier circuits and power supply lines each having one end connected to the power supply terminals of said switch circuits being formed on one dielectric layer to constitute a power supply line layer, and pluralities of power supply lines extending in two or more of triangular regions obtained by diagonally quartering the dielectric layer having said power supply line layer; a first ground electrode being arranged on the side of said main surface with respect to said power supply line layer, said first ground electrode overlapping at least part of said power supply lines in a lamination direction; a second ground electrode being arranged on the opposite side of said first ground electrode with respect to said power supply line layer, said second ground electrode overlapping at least part of said power supply lines in a lamination direction; and said high-frequency-signal-treating circuits being arranged on the opposite side of said power supply line layer with respect to said second ground electrode.
