    • In a radio apparatus, the band of a loop filter of a synthesizer in a blank channel searching state is narrower than the band in a communicating state. In addition, a radio wave environment is measured. A characteristic necessary for the radio apparatus is determined corresponding to the measured-radio wave environment. The power is controlled corresponding to the performance of the radio apparatus. Thus, the power consumption is decreased. In addition, the efficiency of the output power is improved. In the radio apparatus, the current consumption of a power amplifier PA is measured. A matching circuit (LNA or MIX) of the antenna is adjusted with the measured result so as to decrease an antenna loss. In the radio apparatus, a DC offset is removed from the transmitted power and the reflected wave. When the DC offset is removed using an AC coupling capacitor, the deterioration of the frequency characteristic of the receiving portion is compensated with a capacitor in a digital signal process. In the radio apparatus, a transmission power detecting portion is structured as an IC chip. The transmission power detecting portion detects the transmission power corresponding to leakage currents in the power supply of the IC chip and the ground. Thus, when the power is detected, a power loss is suppressed. Consequently, the power consumption of the radio apparatus can be decreased.

    • Disclosed is a method for gettering a transition metal impurity diffused in a silicon crystal at ultra high-speeds to form deep impurity levels therein. The method comprises codoping two kinds of impurities: oxygen and carbon, into silicon, and thermally annealing the impurity-doped silicon to precipitate an impurity complex of an atom of the transition metal impurity, the C and the O, in the silicon crystal, so that the transition metal impurity is confined in the silicon crystal to prevent the ultra high-speed diffusion of the transition metal impurity and electrically deactivate deep impurity levels to be induced by the transition metal impurity. The present invention makes it possible to produce a silicon semiconductor device free of adverse affects from a transition metal impurity, such as Co, Ni or Cu, mixed in a silicon crystal during a process of forming the silicon single crystal, or such as Cu mixed in a silicon wafer during a process of printing a Cu wiring, which has not been able to be completely eliminated from the silicon crystal through conventional techniques.
