Abstract:
1. An amplification system, comprising: a bandpass filter operative to filter at least one of an input digital bitstream and an amplified signal and to generate a filtered signal, the bandpass filter being configured to provide constant input impedance over a passband associated with the input signal, the bandpass filter being configured to provide constant input impedance over a stopband associated with shaped-noise energy, thereby increasing at least one of signal-to-noise ratio and signal-to-distortion ratio associated with the filtered signal; and an amplifier coupled with the bandpass filter, the amplifier amplifying at least one of the filtered signal and the input digital bitstream to provide the amplified signal; wherein the input digital bitstream comprises at least one of a Long Term Evolution (LTE) bitstream set and a Two-tone bitstream set.
