    Abstract: An apparatus comprises a first RF port, a second RF port, a first resonator circuit and at least one second resonator circuit. The first resonator circuit and the second resonator circuit may be connected between the first RF port and the second RF port. The first resonator circuit may comprise a first inductor, a first capacitor, and a first stacked switch device. The second resonator circuit may comprise a second inductor, a second capacitor, and a second stacked switch device. The first capacitor and the first stacked switch device may be coupled in series across the first inductor. The second capacitor, the second inductor, and the second stacked switch device may be connected in parallel.

    Abstract: An apparatus includes an amplifier circuit and a protection circuit. The amplifier circuit may be configured to generate an output signal by amplifying an input signal received at an input port. The input signal may be a radio-frequency signal. The protection circuit may be configured to (i) generate a detection signal by detecting when a level of the input signal exceeds a corresponding threshold, where the level is a power level, a voltage level or both, (ii) route the input signal away from the input port of the amplifier circuit and disable the amplifier circuit both in response to the detection signal being continuously active at least a first time duration and (iii) route the input signal to the input port of the amplifier circuit and enable the amplifier circuit both in response to the detection signal being continuously inactive at least a second time duration.

    Abstract: An apparatus includes one or more field effect transistors configured as a switch. Each of the one or more field effect transistors comprises one or more source diffusions, one or more drain diffusions, and one or more gate fingers. Each of the one or more gate fingers is disposed between a source diffusion and a drain diffusion. A first electrical connection to the one or more source diffusions is made using one or more source electrodes that extend from a first end for a first length along a long axis of the source diffusions. A second electrical connection to the one or more drain diffusions is made using one or more drain electrodes that extend from a second end for a second length along a long axis of the drain diffusions. The first length of the one or more source electrodes and the second length of the one or more drain electrodes are generally selected to avoid juxtaposition of the one or more source electrodes and the one or more drain electrodes.

    Abstract: An apparatus includes a device comprising a semiconductor junction configured to generate a reference voltage, a voltage divider circuit, a comparator circuit, and a first output circuit. The voltage divider circuit may be configured to generate a first predetermined threshold voltage in response to the reference voltage. The comparator circuit may be configured to generate a first intermediate signal in response to a comparison of the first predetermined threshold voltage and an input signal. The first output circuit may be configured to generate a first output signal in response to the first intermediate signal.

    Abstract: An apparatus comprises an input port, an output port, and a resonant receive switch circuit. The resonant receive switch circuit may be coupled between the input port and the output port. The resonant receive switch circuit may comprise a first switch, a second switch, and an input matching circuit. When the first and the second switches are in a non-conducting state, a signal at the input port is passed to the output port. When the first and the second switches are in a conducting state, the signal at the input port is prevented from reaching the output port.
