    Abstract: An RF switch formed as a micro electro-mechanical switch (MEMS) which can be configured in an array forming a micro electro-mechanical switch array (MEMSA). The MEMS is formed on a substrate. A pin, pivotally carried by the substrate defines a pivot point. A rigid beam or transmission line is generally centrally disposed on the pin forming a teeter-totter configuration. The use of a rigid beam and the configuration eliminates the torsional and bending forces of the beam which can reduce reliability. The switch is adapted to be monolithically integrated with other monolithic microwave integrated circuits (MMIC) for example from HBTs and HEMTs, by separating such MMICs from the switch by way of a suitable polymer layer, such as polyimide, enabling the switch to be monolithically integrated with other circuitry. In order to reduce insertion losses, the beam is formed from all metal, which improves the sensitivity of the switch and also allows the switch to be used in RF switching applications. By forming the beam from all metal, the switch will have lower insertion loss than other switches which use SiO2 or mix metal contacts.

    Abstract: A waveguide structure (10) that provides a transition from a polymeric waveguide (26) to a coaxial connection (48). The coaxial connection (48) includes an outer conductor (50) electrically connected to a top ground plate (36) of the waveguide (26) and an inner conductor (52) that extends into the polymeric material within the waveguide (26). The inner conductor (52) is electrically connected to a capacitive plate (56), and the capacitive plate (56) is electrically connected to an elongated conductive probe (58). The conductive probe (58) is electrically connected to a conductive post (60), which is electrically connected to a bottom ground plate (38) opposite to the top ground plate (36). The conductive probe (58) extends in a direction transverse to the propagation direction of electromagnetic waves, and acts to pick up the energy in the electromagnetic radiation. The capacitive plate (56) provides a shunt capacitance that resonates out the inductance caused by the conductive probe (58) and the inner conductor (52). The conductive probe (58) is positioned relative to a backshort surface (44) of the waveguide (26) a distance that is less than a quarter wavelength of the electromagnetic radiation of interest.

    Abstract: A lanthanum aluminate (LaAlO.sub.3) substrate on which thin films of layered perovskite copper oxide superconductors are formed. Lanthanum aluminate, with a pseudo-cubic perovskite crystal structure, has a crystal structure and lattice constant that closely match the crystal structures and lattice constants of the layered perovskite superconductors. Therefore, it promotes epitaxial film growth of the superconductors, with the crystals being oriented in the proper direction for good superconductive electrical properties, such as a high critical current density. In addition, LaAlO.sub.3 has good high frequency properties, such as a low loss tangent and low dielectric constant at superconductive temperatures. Finally, lanthanum aluminate does not significantly interact with the superconductors. Lanthanum aluminate can also be used to form thin insulating films between the superconductor layers, which allows for the fabrication of a wide variety of superconductor circuit elements.
