Patent ID: 7599190

Claim:
A high-frequency module comprising: a first organic substrate having no glass fibers with conductive portions formed on top and bottom surfaces of the first organic substrate; a second organic substrate having conductive portions formed on top and bottom surfaces of the second organic substrate; a prepreg layer having no glass fibers exclusively located between the first and second organic substrates; an insulating layer formed over the conductive portions formed at the top surface of the first organic substrate and wherein high frequency circuit components are formed over the insulating layer and there is no conductive portion on either the top or bottom surfaces of the first organic substrate located perpendicularly below high frequency circuit components that are formed over the insulating layer; a high frequency integrated circuit located above the high frequency components and wherein conductors transmit electrical signals through the first and second organic substrates and the prepreg layer to conductive pads located beneath the second organic substrate.
