Patent ID: 7355863

Claim:
A high frequency multilayer integrated circuit comprising: a multilayer board including n earth conductor layers (n: integer of two or more than two) and (n-1) dielectric layers each arranged between adjacent earth conductor layers; a first high frequency circuit disposed in one of the most outside earth conductor layers of the multilayer board; a first power-supply/control circuit disposed in the one of the most outside earth conductor layers of the multilayer board; a second high frequency circuit disposed in at least one of the (n-1) dielectric layers and connected to the first high frequency circuit in the multilayer board; a second power-supply/control circuit disposed in another one of the most outside earth conductor layers of the multilayer board; and a third power-supply/control circuit disposed in at least one of the (n-1) dielectric layers at a portion other than a portion at which the second high frequency circuit is disposed, said third power-supply/control circuit being connected, in the multilayer board, to the first and second power-supply/control circuits.
