  • Publication number: 20090101999
    Abstract: An electronic device. The electronic device includes a first electrode and a coating layer. The electronic device is fabricated on a substrate; the substrate has a cavity created in a top surface of the substrate; and the first electrode is electrically coupled to the substrate. The coating layer coats at least part of a substrate surface in the cavity, and the presence of the coating layer results in a mitigation of at least one parasitic leakage path between the first electrode and an additional electrode fabricated on the substrate.

  • Patent number: 7107170
    Abstract: A multiport vector network analyzer calibration employs measurements of an asymmetric reciprocal device to determine a value of a defining parameter of a calibration standard in a set of calibration standards. A method of determining a parameter value determines and reports the parameter value. A method of compensating a calibration determines the parameter value and employs the determined parameter value to optimize a set of error coefficients of an error model of the multiport vector network analyzer. A multiport vector network analyzer that includes a controller, a test set, and computer program executed by the controller, compensates a calibration using the determined parameter value and a set of optimized error coefficients. A calibration compensation system that includes a multiport vector network analyzer, a computer, and a computer program executed by the computer, determines and reports the parameter value.

  • Patent number: 7053640
    Abstract: High port-to-port RF isolation for a test socket in a production RF test environment is achieved by establishing a coaxial-type connection between the test socket and the device under test (DUT). This coaxial-type connection results by at least partially surrounding each port of the DUT with a ground seal connected to RF ground connection. In one embodiment, the ground seal is a metallic base plate of the test socket which surrounds the RF connection to the DUT.

  • Patent number: 6804807
    Abstract: An interface model of a ground-signal-ground (“GSG”) probe is included when simulating an electronic circuit that develops unbalanced ground currents. The interface model of the GSG probe is used to obtain simulated results that more closely match data measured from the electronic device when using the GSG probe.
