  • 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.
