  • Patent number: 10164680
    Abstract: A radio communication device is provided with a VOX function. A reception completion state determination unit determines whether or not a reception unit is in a state of completing reception. A timer starts to measure a predetermined time when the reception completion state determination unit determines that the reception unit is in the state of completing the reception. A VOX level selection unit sets a VOX level at which the VOX function determines that transmission is made to a first VOX level after the timer finishes measuring the predetermined time, and sets the VOX level to a second VOX level smaller than the first VOX level while the timer is measuring the predetermined time.

  • Patent number: 10164582
    Abstract: A linearization circuit that reduces intermodulation distortion in an amplifier output receives a first signal that includes a first frequency and a second frequency and generates a difference signal having a frequency approximately equal to the difference of the first frequency and the second frequency. The linearization circuit generates an envelope signal based at least in part on a power level of the first signal and adjusts a magnitude of the difference signal based on the envelope signal. When the amplifier receives the first signal at an input terminal and the adjusted signal at a second terminal, intermodulation between the adjusted signal and the first signal cancels at least a portion of the intermodulation products that result from the intermodulation of the first frequency and the second frequency.

Embodiments of the present invention provide for dynamically changing the bias current, impedance, and gain, either separately or in combination, during circuit operation to optimize or to reduce power dissipation. The dynamic variations may be implemented by varying the value of a resistance and/or a capacitance by opening switches across one or more portions of the resistance. Also, the dynamic variations may include setting any of the gain, bias current, or impedance parameters of the receiver circuit in between a high and low level, followed by adjusting the parameter up or down in response to a desired signal and an interferer signal.
