  • Apparatus and method for high performance wide-band power amplifier monolithic microwave integrated circuits
    Patent number: 5349306
    Abstract: A distributed amplifier produced from monolithic microwave integrated circuit (MMIC) processes employs a bandpass filter structure as opposed to a low-pass filter network to enhance gain, efficiency and output power over wideband operation of 6 GHz to 18 GHz. Derivation of the preferred embodiment is shown from a three port circuit employing bandpass filter image-parameter half-sections.

  • Metal-insulator-metal (MIM) capacitor-around-via structure for a monolithic microwave integrated circuit (MMIC) and method of manufacturing same
    Patent number: 5208726
    Abstract: A metal-insulator-metal (MIM) capacitor for monolithic microwave integrated circuit applications of the capacitoraround-via type having a bottom plate 36, a dielectric 40, and a top plate 44 which substantially surround, but do not physically overlay, via hole 32 and provide a low-inductance connection between a frontside MIM capacitor and a backside ground plane.
