Abstract
A gain compensating circuit for a feedforward cancellation amplifier which compensates inbalance (i.e., changes in gain of the power bank amplifier) due to changes in operating conditions or failures in various circuits in the amplifier. The gain compensating circuit compensates the gain variations and restores balance and fundamental cancellation to the circuit while retaining the highly linear characteristics of the amplifier.
