In this paper we present a wideband harmonic rejection (HR) RF receiver design. Both gain mismatch and phase mismatch of the HR mixer have been calibrated using a design and calibration method called extended statistical element selection to achieve best-in-class HR ratio (HRR) performance. The achieved concurrent 3rd order HRR and 5th order HRR are greater than 80 dB and 70 dB, respectively, after calibration. The even order HRR is also calibrated to greater than 80 dB. A single calibration performed at 750 MHz was further observed to be effective over more than two octaves of bandwidth with greater than 70 dB HRR. The receiver was manufactured in 65 nm CMOS technology. Input RF frequency range was 0.15-1 GHz and the receiver consumes 64 mW at 1 GHz. Noise figure is 3.2 dB and out-of-band IIP3 is -7 dBm at a total gain of 48 dB.
