    摘要： 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.

    摘要： 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 switch and an input matching circuit. When the switch is in a non-conducting state, a signal at the input port is passed to the output port. When the switch is in a conducting state, the signal at the input port is prevented from reaching the output port.

    摘要： 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.

    摘要： 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.

    摘要： An apparatus includes an amplifier and a gain control circuit. The amplifier may be configured to provide multiple gain steps. The gain control circuit may be configured to provide fast and precise changes between the multiple gain steps of the amplifier. The gain control circuit may be further configured to change an impedance of the amplifier to switch between the gain steps. The gain control circuit may be further configured to compensate for changes in frequency response related to changing the impedance. The gain control circuit may be further configured to inject a complementary charge to an input of the amplifier to correct a bias voltage deviation and a transient caused by the gain control circuit.
