<p>A power controller provided with a power level adjusting circuit (11) for adjusting the input signal according to a control voltage to a desired level and outputting the adjusted input signal, a control voltage generating circuit (12 - 18) which compares the present output power of the power level adjusting circuit (11) with a desired power level and generates a control voltage in accordance with the comparison result, a low-pass filter (19a) which operates with one of a 1st time constant and a 2nd time constant smaller than the 1st time constant, filters the control voltage generated by the control voltage generating circuit (12 - 18) and supplies it to the power level adjusting circuit (11), and a filter control means (19b) which allows the low-pass filter (19a) to operate with the 2nd time constant at the rise of the output power and allows the low-pass filter (19a) to operate with the 1st time constant after the rise of the output power.</p> |
