  • Patent number: 5115245
    Abstract: A microwave radar transceiver assembly (30) includes a monolithic microwave integrated circuit (MMIC) chip (58) having a coplanar waveguide transmssion lines (100, 102, 104) formed on the same surface (58a) as the electronic elements thereof. Coplanar waveguide transmission lines (68, 70, 72) are also formed on a surface (62a) of a substrate (62). The transceiver chip (58), in addition to other chips (56, 60), are mounted on the substrate (62) in a flip-chip arrangement, with the respective surfaces (58a, 62a) on which the transmission lines (100, 102, 104; 68, 70, 72) are formed facing each other.

  • Patent number: 5087896
    Abstract: A coplanar waveguide based microwave monolithic integrated circuit (MMIC) oscillator chip (14) having an active oscillator element (16) and a resonant capacitor (18) formed thereon is flip-chip mounted on a dielectric substrate (12). A resonant inductor (22) is formed on the substrate (12) and interconnected with the resonant capacitor (18) to form a high Q-factor resonant circuit for the oscillator (10). The resonant inductor (22) includes a shorted coplanar waveguide section (24) consisting of first and second ground strips (24b,24c), and a conductor strip (24a) extending between the first and second ground strips (24b,24c) in parallel relation thereto and being separated therefrom by first and second spaces (26a,26b) respectively. A shorting strip (24d) electrically interconnects adjacent ends of the conductor strip (24a) and first and second ground strips (24b,24c) respectively.

  • Patent number: 3986153
    Abstract: An active millimeter wave integrated circuit including a thin non-metallic waveguiding layer mounted on an image plane and having an opening therein which exposes a given area of the image plane. An active solid state device, such as a millimeter wave diode, is mounted on the exposed area of the image plane, and millimeter wave energy is coupled to and from the device into the waveguiding layer by way of both a metallic ribbon (or wire) bonded to the active device and a connecting metallization pattern atop the waveguiding layer. This metallization pattern may assume various geometries corresponding to functional components such as low-pass filters, resonators, stepped or tapered metallized transitions, and the like, and also provides the desired impedance matching and efficient energy coupling between the active device and the waveguiding layer.
