  • Low noise amplifier circuit with phase matched switch topology
    Patent number: 6680647
    Abstract: An amplifier and bypass switch circuit includes a circuit input, a circuit output, an amplifier and a switching circuit. The amplifier has an amplifier control input, and a first amplifier output. The amplifier control input is connected to the circuit input. The amplifier output is connected to the circuit output. The switching circuit includes a control input, a switch input, a switch output and a phase matching network. The switch output is connected to the circuit output. The switch input is connected to the circuit input. The phase matching network preserves phase information when the amplifier and bypass switch circuit switches between an amplifier mode and a bypass mode.

  • Common device node balun grounded balanced amplifier
    Patent number: 6606002
    Abstract: An amplifier circuit includes an amplifier stage and a balun stage. The amplifier stage includes a common node connected to an external ground. An inductance is located between the common node and the external ground. The balun stage is connected to the amplifier stage. The balun stage includes a balun tail. The balun tail is directly connected to the common node of the amplifier stage so that a resulting connection between the balun tail and the common node bypasses the inductance between the common node and the external ground.

  • Duplexer with a differential receiver port implemented using acoustic resonator elements
    Publication number: 20030112768
    Abstract: A duplexer includes an input/output line, a receive segment and a transmit segment. The transmit segment is connected to the input/output line. The receive segment includes a balun and a differential filter. The balun includes a first output, a second output, a first transmission line and a second transmission line. The first transmission line is connected between the input/output line and the first output. The second transmission line is connected between the input/output line and the second output. The differential filter is connected to the first output and the second output. The differential filter shorts the first output and the second output at transmit band frequencies of the duplexer.
