PURPOSE:To obtain the power amplifying device which has optimum response and high-level stability for a given load value by inputting the value of a connected load to the device in advance. CONSTITUTION:A control parameter generating means 400 which generates and sets a control parameter and a load parameter input/display means 300 are added to a conventional device. Values of resistance and reactance as components of load impedance are inputted from the load parameter input/ display means 300 and applied to the control parameter generating means 400. The control parameter generating means 400 receives the inputted value of load impedance by a CPU 401 and calculates the value of the control parameter on the basis of the inputted impedance value according to a program stored in a ROM/RAM 402. Consequently, the optimum control parameter for the given load impedance can be set and optimum response is obtained in the output. |
