<p><P>PROBLEM TO BE SOLVED: To provide a frequency hopping transmitter which is capable of automatically keeping a transmission output fixed by dividing the whole of the frequency hopping transmitter to individually calculate amplification factors of a power amplification part and amounts of loss of a filter circuit. <P>SOLUTION: A control part 46 of a frequency hopping transmitter 100 automatically calculates an amplification factor of a power amplification art 35 and the amount of loss of a filter circuit 41, which correspond to each hopping frequency, on the basis of outputs detected by detectors 36 and 42 and automatically sets an output of a transmission part on the basis of the calculated amplification factor and amount of loss so that a prescribed transmission output is transmitted from the filter circuit, and therefore, the prescribed transmission output is automatically transmitted from the filter circuit. Consequently, the whole of the frequency hopping transmitter is properly divided to be able to automatically keep the transmission output fixed without requiring much labor. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
