procedure and device for stabilisation of reinforcement in a styrslinga in a personal communications

摘要

A gain stabilization loop performs discrete time adjustments to the RF amplifier forward gain path of a closed-loop transmitter power control system based on a measurement of the gain in the control loop. The stabilization of the RF amplifier gain allows the transmitter's control loop to remain functional over varying gain Conditions which are prevalent within stages of the RF amplifier gain path. The effects of gain changes within the stages due to part-to-part variations. and temperature effects are minimized or eliminated by this gain trimming.
