摘要: Abstract RF Amplifier with Signal-Level Control, and Radio Transmitter Equipped Therewith An power amplifier is known which has a digital feed-back control system for generating uniform pulses following each other successively in time. Also an TDMA radio signal whose level changes from time interval to interval. The object of the invention design stably controlled controlling characteristic signal, particularly desired-level predetermined anew one next. novel (PA) circuit (CC) controls change (SL) (Pin, Pout) by evaluating actual-level differently within two or more segments (AT, GT) respective (T1[k]). Advan-tageously, action dur-ing first segment (GT), step next, differs that during second (AT), constant. Temporary storage correction values permits stable off-line control. (Fig. 1)
