  • Temperature compensated power detector
    Patent number: 7890065
    Abstract: A temperature-compensated power detector for detecting variations in the power level of an RF signal. The temperature-compensated power detector includes a detector circuit and a temperature compensating circuit. The detector circuit detects the power level of an RF signal and provides an output voltage that corresponds to the power level of the RF signal. The temperature compensating circuit ensures that the output voltage of the temperature-compensated power detector is independent of changes in the temperature.

  • Voltage regulated power supply system
    Patent number: 7564230
    Abstract: A voltage regulator for providing a regulated voltage is disclosed. The voltage regulator comprises an error amplifying module and a regulator. The error amplifying module provides a reference voltage, based on an output voltage to be regulated. The regulator provides a regulated output voltage based on the reference voltage. Voltage regulator provides stable output voltage against variations caused by power supply and load with a defined temperature coefficient.

  • Active clamping circuit for power amplifiers
    Patent number: 6580321
    Abstract: An active clamping circuit for a multi-stage power amplifier includes a feedback circuit which affects the gain of the amplifier. The feedback circuit feeds an output via a filter and a clamping transistor to an input of at least one stage of the power amplifier. The output fed to the filter and clamping transistor may be tapped from one or more diodes belonging to a diode stack connected to the power amplifier's output.
