A 0.1–5.0GHz self-calibrated SDR transmitter with −62.6dBc CIM3 in 65nm CMOS
A 0.1-5.0GHz self-calibrated SDR transmitter is presented. A complete self-calibration scheme is proposed to alleviate non-ideal effects, including RF operation frequency deviation, output power control, LO leakage and image rejection. A power mixer front-end and a V-I converter with 3rd-order nonlinearity cancellation are introduced to achieve -62.6dBc CIM3 at 5.3dBm output power in LTE band42. A Class-AB/F dual-mode PA is integrated for narrowband applications. With the self-calibration, the transmitter has obtained good robustness in RF operation frequency self-tuning, LO leakage and image rejection performance over 0.1-5.0GHz, and achieved 24.5dBm Pout with 0.7% EVM, 20dBm Pout with 1.6% EVM, 6.2dBm Pout with 2.1% EVM for GSM/EDGE/LTE signals, respectively.
