The amplifier achieves linearity suitable for wideband wireless standards, with peak efficiency of 43.5% at 1.95GHz and up Rf•I 2/R1 = 1 and TR = 0.1%, then the worst case DC CMRRDIFF will be 54 dB. Rf•I 2/R1 = 1 and T R = 1%, then the worst case DC CMRRDIFF will be only 34 dB. Moreover, RSEN should be much less than R1 and R2 in order to minimize resistive loading effect.
