Title: Spread spectrum transmitter
Inventor: TAUCHI NOBUTAKA
IPC: H04B1/707
Filed: 2001-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a spread spectrum transmitter whose data storage capacity is reduced. SOLUTION: A power controller 10h obtains a power level of a transmission signal on the basis of a digital signal from an analog/digital converter 120 by each transmission power measurement period and updates the variable gain of gain control amplifiers 45, 46 to make the power level approach a target value. An output of 1st - 3rd transmission signals is inhibited for the transmission power measurement period and only a control signal is outputted. In this case, since the combination of 1st and 2nd gain parameters βd, βc is constant, the output waveform of the gain control amplifiers 45, 46 is constant.  Since the level of the digital signal corresponding to a target power level is obtained, a memory 10k has only to store one kind of a transmission power map with transmission power data by each target transmission power level and the storage capacity of data of the memory 10k can be decreased.
