Abstract
A device for linear transmitter 150 with improved loop gain stabilization. The linear transmitter 150 includes a main amplifier loop 178 and an auxiliary loop 176. The device includes an adjustable driver 159, connected within the main amplifier feedback loop 178 and further connected to the auxiliary loop 176. The adjustable driver 159 receives an input signal from main amplifier feedback loop 178, amplifies it in accordance with a gain control signal received from the auxiliary loop 176 and provides the amplified signal to main amplifier feedback loop 178.
