  • Patent number: 8135364
    Abstract: Communication equipment includes a circuit generating an RF input signal; a PA receiving a supply voltage, receiving the RF input signal, and providing an amplified version of the RF input signal as an output signal that is associated with an output power of the communication equipment; and an output circuit that includes an antenna for transmitting the output signal. The communication equipment also includes: a voltage detector circuit including sensing circuitry for sensing the supply voltage and a comparator for comparing the supply voltage to a first voltage threshold and generating a control signal when the supply voltage exceeds the first voltage threshold; and a disabling circuit coupled to the voltage detection circuit for disabling a portion of the communication equipment in response to the control signal to maintain output power of the communication equipment below a maximum output power level.

  • Patent number: 7860196
    Abstract: A method and circuit are described for estimating I and Q amplitude imbalance occurring in a signal received by a direct conversion receiver (DCR). The DCR generates a mixing signal having a frequency substantially the same as the carrier signal of the signal received by an antenna. A mixing module mixes the mixing signal at different phases with the received signal to generate I and Q baseband signals. A frequency offset circuit generates an offset signal having a frequency offset from the carrier signal frequency. A coupling circuit selectively decouples the antenna from the DCR and couples the offset signal to the mixing module to generate a baseband test signal in the I and Q signal paths for determining an imbalance in the amplitudes of the baseband test signals between the I and Q signal paths.
