Abstract
An apparatus in one example comprises a differential amplifier and a differential mixer. The differential amplifier is configured to receive a multi-octave differential input signal and output an amplified multi-octave differential output signal. The differential amplifier is also configured to substantially reduce second order harmonic distortion of the amplified multi-octave differential output signal through common mode rejection. The differential mixer configured to multiply the amplified multi-octave differential output signal with a local oscillator input signal and output an up-converted sub-octave differential output signal. The multi-octave differential input signal and the up-converted sub-octave differential output signal comprise a substantially same bandwidth.
