“…Furthermore, owing to the several stacked transistors, a larger supply voltage is required to avoid the compression of the output voltage amplitude, which inevitably influences the power consumption of whole circuit. In [4], [9] a two-stage subharmonically base-pumped transconducance mixer is introduced that reaches to a maximum -1 dB and 9 dB conversion gain at D-band and V-band using a -1 dBm and 2 dBm LO power, respectively. This type of mixer utilizes the internal mixing of RF signal with the second-or higher-order harmonics of the LO signal, generated by nonlinearities of transistor itself.…”

This paper demonstrates a wideband, subharmonic down converting mixer using a commercial 130-nm SiGe-BiCMOS technology. The mixer adopts a frequency doubling LO-stage, a differential switched-transconductance RFstage, on-chip LO and RF baluns, and two emitter-follower buffer-stages. The measured results exhibit a maximum conversion gain up to 2.6 dB over the frequency range of 100 to 140 GHz with a LO power of 5 dBm. The mixer achieves an input referred 1-dB compression point of-7.2 dBm, with a DC power of 46.3 mW, including 26.7 mW for buffer-stages. It demonstrates also up to 12 GHz 3-dB IF bandwidth, which to the authors' best knowledge, is the highest obtained among active sub-harmonic mixers operating above 100 GHz. The chip occupies 0.4 mm 2 , including pads.

“…Therefore, a power hungry IF buffer amplifier is usually exploited at the output, which correspondingly leads to a high power consumption, e.g. 120 mW [4] and 262 mW [9]. This paper presents a high conversion gain and a broadband transconductance SHM based on a bottom-LO frequency doubler to operate at 100 to 140 GHz frequency range.…”

Beyond fifth generation (5G) communication systems aim towards data rates in the tera bits per second range, with improved and flexible coverage options, introducing many new technological challenges in the fields of network architecture, signal processing, and radio frequency front-ends. One option is to move towards cell-free, or distributed massive Multiple-Input Multiple-Output (MIMO) network architectures and highly integrated front-end solutions. This paper presents an outlook on beyond 5G distributed massive MIMO communication systems, the signal processing, characterisation and simulation challenges, and an overview of the state of the art in millimetre wave antennas and electronics.
