In this paper, we propose a ball grid array (BGA) module with integrated 3D-printed plastic lens and dedicated 120 GHz OOK transceiver for 5G Backhaul/Fronthaul applications. The problem to be addressed is the following: 5G future networks will need backhaul/fronthaul 10Gbps wireless links and it's mandatory to design cost-effective and energy efficient solutions. The proposed solution is made of 3D-printed plastic lens antenna and cheap 7×7×0.362 mm 3 BGA module integrating a 2×2 array of aperture-coupled patch antennas as the source of the lens. The measurement results of the full system confirm the expected performance of the plastic lens: a-10dB matching and a 28 dBi realized gain from 114 to 140 GHz. The active measurements allows a Tx/Rx link >12Gbps data transmission with <10-6 BER at nearly 5m. This link is realized with an energy-efficiency better than 1.6 pJ/b/s which is at least 40 times better than state-ofthe-art high-speed existing TRx's. Those promising results pave the way for future cost-effective and low consumption backhaul/fronthaul systems for 5G communications. What is the novelty of your work over the existing work (100 words)? So far, several wireless links at 120 GHz have been deployed by various authors with very high Gbps speed but at the expense of high DC consumption and bulky material which is in turn correspond to weak integration of the full-system. The novelty of our work lies in the fact that every communicating block has been optimized in conjunction with all the other nearby elements, strongly taking into account cost and integration capability. Therefore a Tx/Rx link >12Gbps data transmission with <10-6 BER at nearly 5m. This link is realized with an energy-efficiency better than 1.6 pJ/b/s which is at least 40 times better than state-of-the-art high-speed existing TRx's.

This paper presents a 60GHz heterodyne receiver architecture with IF sub-sampling. A particular arrangement of the frequency plan allows anti-alias filtering by the chargedomain subsampler. Down-conversion, channel filtering and IQ demodulation are merged into a unique operator without any extra cost in terms of area and power consumption. The proposed architecture is able to receive up to 4 bonded channels and complies with the requirements of the standards for 60GHz wireless communications. The result of this study shows that subsampling is a good candidate for low power and configurable receivers for mmW wireless communications.I.
This paper presents the architecture, the implementation details and the measurement results of an IF to DC subsampler for 60 GHz applications. The proposed subsampler performs downconversion, IQ demodulation and out-of-band filtering within a unique operation. An 802.11ad (WiGig) channel at a fixed 21.12 GHz IF frequency is subsampled using a 7.04 GHz clock. The 1.76 GS/s analog to digital conversion is directly performed in baseband after FIR filtering and decimation. The charge domain subsampler and FIR filter provide additional immunity to perturbations at no extra hardware cost. Digitally controlled delay lines set the phase of the sampling clock to reach the best sampling instant. In conclusion, subsampling-based back-ends can be promising candidates for low power, low cost and digitally synchonized receiver architectures
