Abstract:
An MMIC package comprising:a base substrate having top and bottom surfaces;a composite capacitor substrate having front and rear surfaces mounted on said base substrate; andan MMIC bare chip having front and rear surfaces, said front surface being bonded onto said composite capacitor substrate,said top surface mounting thereon a signal terminal, a source terminal and a GND pattern,said bottom surface mounting thereon a plurality of external terminals, each connected via through-holes to said signal terminal, said source terminal and said GND pattern,said front surface of the MMIC bare chip mounting thereon a signal terminal and a source terminal,said whole rear surface of the MMIC bare chip mounting thereon a GND pattern,said front surface of said composite capacitor substrate mounting thereon a planar metal pattern connected through a bump with said source terminal of the front surface of said MMIC bare chip, and a metal pad connected through a bump with said signal terminal on the front surface of said MMIC bare chip,said rear surface of said composite capacitor substrate mounting thereon a planar metal pattern opposing to said planar metal pattern of the front surface of said composite capacitor substrate and connected with said GND pattern on the top surface of said base substrate, a metal pad for a signal connected via a through-hole with said metal pad on the front surface of said composite capacitor substrate and further connected with said signal terminal of the top surface of said base substrate, and a metal pad for a power source connected via a through-hole with said planar metal pattern on the front surface of said composite capacitor substrate and further connected with said source terminal of the top surface of said base substrate.
