POWER CONTROLLER

PURPOSE:To smooth the rising characteristic of transmission power and to prevent adjacent channel leak power from being degraded by the band spread of a conventional carrier. CONSTITUTION:When starting transmission by a control signal 14, a voltage is applied from a voltage generation circuit 13, and the output voltage of the voltage generation circuit 13 is changed by a control signal 10 so as to be close to a voltage at the time of raising a control signal 15. When the control signal 15 rises, a changeover switch circuit 11 and a hold circuit 12 are connected, and the changeover switch circuit 11 switches an output from the voltage generation circuit 13 to an output from an error detection circuit 9 corresponding to the control signal 14.
