Kurzfassung englisch:
In most publications on the behavior of the cancelation loops within a feedforward amplifier (FFA) the use of frequency independent nonlinear amplifiers was assumed. The only frequency dependent effect treated in detail was a time delay mismatch occurred within these loops. This paper discusses the balancing of a cancelation loop (CL) in the presence of a dynamic nonlinear (DN) device. Using this result the behavior of this structure is analyzed and the decomposition of the residual output signal is performed. A comparison of the major contributors to this output signal is presented and steps for a further reduction of the residual signal power are discussed.
