“…Compared with the traditional superheterodyne structure, it has the advantages of lower cost, higher integration, lower power consumption, simpler structure, etc. Therefore, there are many high performance zero-IF mixers proposed in recent years [1]- [5]. However, most of the proposed zero-IF mixers have difficulties in solving the inherent serious problems in the practical application, including DC offset, flicker noise, second-order intermodulation distortion (IMD2) completely, which also limits the performance of the zero-IF mixer.…”

This paper presents a high performance I/Q zero intermediate frequency (IF) mixer with a second-order input intermodulation point (IIP2) calibration technique in 45nm SOI CMOS process. A behavioral model of the mixer is established to analyze the sources of the second-order intermodulation distortion (IMD2). Based on the analysis, a high accuracy load resistance modulation array is applied to achieve excellent IIP2 performance. The frequency of the local oscillator (LO) signal is 3.5GHz, while the RF input signal frequency range is 3.4GHz∼3.6GHz. Simulation results show that the proposed zero-IF mixer achieves a conversion gain of more than 9.2dB with the input 1dB compression point of -11.28dBm. Noise figure is about 16.9dB at 10kHz and lower than 11.6dB at the frequency above 1MHz. The IIP2 of the circuit is larger than 66dBm after the calibration, which increases more than 40dBm.

“…Zero-IF transmitters are widely used in the design of millimeter wave transceivers due to their strong anti-interference ability, large bandwidth, and ability to cope with diversified scene requirements [13,14]. Although zero-IF TXs simplify the architecture of the system, implementing a zero-IF RF front-end presents the problem of insufficient suppression of image signals and LO leakage signals, especially when the operating frequency rises to the millimeter wave band.…”

This article presents a transmitter (TX) front-end operating at frequencies covering 40–50 GHz, including a differential quadrature mixer with integrated amplitude and phase imbalance tuning, a power amplifier, and a detection mixer (DM) that supports local oscillator (LO) leakage signal or image signal calibration. Benefiting from the amplitude and phase imbalance tuning network of the in-phase quadrature (IQ) signal generator at the LO input, the TX exhibits more than 30 dBc image signal rejection over the full frequency band without any post-calibration. Based on the LO leakage signal fed back by the DM integrated at the RF output, the LO leakage of the TX has been improved by more than 10 dB through the LO leakage calibration module integrated in the quadrature mixer. When the intermediate frequency (IF) signal is fixed at 1 GHz, the TX’s 1 dB compressed output power (OP1 dB) is higher than 13.5 dBm over the operating band. Thanks to the LO leakage signal calibration unit and the IQ signal generator, the TX is compliant with the error vector magnitude (EVM) requirement of the IEEE 802.11aj standard up to the 64-quadrature amplitude modulation (QAM) operating mode.
