  • Ultra Broadband 10-W CW Integrated Limiter
    Publication number: 20080157896
    Abstract: The invention provides a novel broadband power limiter having improved frequency characteristics and power capacity, suitable for use with GaAs low-noise amplifier circuits. The power limiter includes a shunt diode circuit and two impedance transformers. The first transformer is a step-down impedance transformer connected between the shunt diode circuit and the input to the limiter, and the second transformer is a step-up impedance transformer connected between the shunt diode circuit and the output of the limiter. The invention further provides a method for limiting the power of an input signal, comprising the steps of: transforming the input signal from the input impedance to an intermediate impedance; shunting a portion of the input signal to ground; and transforming a remaining portion of the input signal from the intermediate impedance to an output impedance.

  • METHOD FOR TERMINAL CONFIGURATION OVER A RADIO CONTROL CHANNEL
    Publication number: 20080095103
    Abstract: An embodiment is a method for configuring a terminal (e.g., a radio) over a radio control channel. Instead of requiring on-site technicians to physically connect to the radios or error-prone and time consuming data calls to individual radios, an embodiment broadcasts software and configuration data as part of one or more radio control channel messages. As the radio control message or multiple messages are broadcast, any radio listening to the radio control message(s) may be configured. Additionally, radios of a particular type will be configured to use the same version of software and configuration data.

  • Method and mechanism for tuning dielectric resonator circuits
    Patent number: 7352263
    Abstract: The invention comprises a technique and associated mechanisms by which dielectric resonator circuits, such as filters, can be tuned in both frequency, bandwidth or both without the need for irises, tuning screws and/or tuning plates. In accordance with the invention, the positions of the dielectric resonators are adjustable relative to each other within the cavity in multiple ways, including vertically and horizontally. The dielectric resonators also may tilt relative to each other. Furthermore, an off-center longitudinal hole can be machined in one or more of the dielectric resonators so as to make the electromagnetic field of the resonator non-uniform so that the dielectric resonator can be rotated about its longitudinal axis to alter the coupling between dielectric resonators.
