Abstract

An amplification system including a high gain amplifier, filter module and low gain amplifier. The high gain amplifier for receiving an input RF signal and processing the input RF signal to produce a first amplified signal while the high gain amplifier is operating near its saturation point. The filter module having at least one band pass filter to receive the first amplified signal and process the first amplified signal to remove unwanted characteristics of the first amplified signal to produce a processed first amplified signal. The low gain amplifier receiving the processed first amplified signal and processing the processed first amplified signal to produce a second amplified signal that has an increase in signal strength over the processed first amplified signal while the low gain amplifier is operating near its saturation point.
