  • Broadband integrated single ended to differential active balun with an n-Way power splitter, DC power shutdown circuit, and /or a default-on port
    Patent number: 9401770
    Abstract: An apparatus comprising a switch, a balun and a splitter. The switch may be configured to provide (i) a first signal on a first path when a power signal is not present and (ii) a second signal on a second path when the power signal is present. The first path activates only the first signal. The second path activates only the second signal. The balun circuit may be configured to convert the second signal to a differential signal. The splitter circuit may be configured to generate a plurality of differential output signals in response to the differential signal.

  • Active field effect transistor limiter
    Patent number: 8937501
    Abstract: An apparatus having a detector and a circuit is disclosed. The detector may be configured to generate a control signal in response to a voltage level of an input signal. The circuit may be configured to (i) connect the input signal to a reference signal with a first impedance in response to the control signal in an asserted state and (ii) connect the input signal to the reference signal with a second impedance in response to the control signal in a deasserted state. One or more transistors in the circuit are generally biased to an off state while the control signal is in the deasserted state.

  • Switch configuration for default-on N-way active splitters
    Patent number: 8614600
    Abstract: An apparatus comprising an amplifier and a switch network. The amplifier may be configured to generate a plurality of output signals in response to an input signal. The switch network may be configured to provide (i) a first path when a power signal is not present and (ii) a second path when said power signal is present. The first path may activate a first of the plurality of output signals. The second path may activate all of the plurality of output signals. An impedance may be connected to the amplifier only when the first path is activated.
