摘要： The object of the invention is to design a stably controlled RF amplifier for controlling the level characteristic of an RF signal, particularly a TDMA radio signal, whose desired-level characteristic is predetermined anew from one time interval to the next.An RF amplifier (PA) has a control circuit (CC) which controls a change of the level characteristic (SL) of an RF signal (Pin, Pout) from time interval to time interval by evaluating the actual-level characteristic of the RF signal differently within two or more segments (AT, GT) of the respective time interval (T1[k]). Advantageously, the control action of the RF amplifier during a first segment (GT), in which the signal level changes from one step to the next, differs from that during the second segment (AT), in which the signal level is constant. Temporary storage of correction values permits stable off-line control.
