In this paper, we present a highly linear direct in-phase/quadrature (I/Q) up-conversion mixer for 5G millimeter-wave applications. To enhance the linearity of the mixer, we propose a complementary derivative superposition technique with pre-distortion. The proposed up-conversion mixer consists of a quadrature generator, LO buffer amplifiers, and an I/Q up-conversion mixer core and achieves an output third-order intercept point of 15.7 dBm and an output 1 dB compression point of 2 dBm at 27.6 GHz, while it consumes 15 mW at a supply voltage of 1 V. The conversion gain is 11.4 dB and the LO leakage and image rejection ratio are −56 dBc and 61 dB, respectively, in the measurement. The proposed I/Q up-conversion mixer is suitable for 5G cellular communication systems.

“…Furthermore, the output IP3 (OIP3) is than 11 dBm. To suppress the LO leakage and enhance the CG and image rejection ratio (IRR), transformers and high-precision polyphase filters are used [18,19]. These up-conversion mixers provide high LO leakage and IRR, but the linearity performance is limited.…”

A mixer is an indispensable device in the RF transceiver system. Along with the rapid development of mobile communication technology, the demand on the RF mixer for compatibility with multiple communication standards and functional diversity is increasing. As a result, the mixer with wider bandwidth, lower noise, higher linearity, and less power consumption is urgently needed.In the article, the basic principle and the circuit architectures of the mixer are reviewed, including the essential performances such as linearity, noise, gain, bandwidth, and so forth. In addition, several aspects are presented, compared, and discussed with particular emphasis on optimization design approach and performance. Current design and fabrication challenges, future development, application areas of the mixer and visions for the mixer are also discussed in this review.

A front‐end MMIC working at 37–43.5 GHz for 5G high‐performance channel emulator is presented in this paper. The chip is fabricated in a 0.1‐μm commercial GaAs pHEMT process and integrated with a passive star mixer and a local oscillator (LO) chain, which is composed of a frequency tripler, a bandpass filter, a power amplifier, and an LO filter. The 10.5 GHz intermediate frequency (IF) signal is upconverted with the high frequency LO signal of 48–54 GHz through a passive double‐balanced star mixer, which can output 37–43.5 GHz radiofrequency signal. The high frequency LO can avoid the increase of bit error rate caused by the frequency band of input signal covering IF frequency. The conversion gain of −11.2 to −9.7 dB, the OP1‐dB of −0.26 to 1.7 dBm are achieved and the front‐end chip occupies an area of 2.78 × 0.9 mm2.
