Abstract:
A power control apparatus comprising:a power level adjusting circuit for adjusting an input signal to a desired power level in accordance with a control voltage to output the obtained result;a control voltage generating circuit for comparing a current output power from said power level adjusting circuit with a target power level to generate said control voltage based on a result of comparison;a low-pass filter operating in accordance with either a first time constant or a second time constant smaller than said first time constant, for filtering said control voltage generated by said control voltage generating circuit to be supplied to said power level adjusting circuit; andfilter controlling means which receives said control voltage and in response to said control voltage causes said low-pass filter to operate in accordance with said second time constant at a first transition of said output power of said power level adjusting circuit and for causing said low-pass filter to operate in accordance with said first time constant after the first transition of said output power of said power level adjusting circuit.
