RF REPLICATOR FOR ACCURATE MODULATED AMPLITUDE AND PHASE MEASUREMENT

摘要

The disclosure provides a communication circuit including an amplification circuit, a replicator circuit, and a correction circuit. Specifically, the amplification circuit generates an amplified signal. The replicator circuit emulates the amplification circuit and generates a replicated signal that approximates the amplified signal. The replicated signal is used by the correction circuit to generate control signals for controlling the amplification circuit.
