“…Considering the power consumption for the connections, the power consumption of a 60 GHz transceiver is less than 0.3 watts [39]. If all 20K transceivers on 10K servers are operating at their peak power, the collective power consumption becomes 6 kilowatts.…”

“…The workhorse of communication in this new design is a directional, beam-formed 60 GHz RF communication channel characterized by high bandwidth (4 − 15 Gbps) and short range (≤ 10 meters). New 60 GHz modems [39,37] based on standard 90nm CMOS technology make it possible to realize such channels with low cost and high power efficiency (< 1W). Directional (25 • -60…”

We introduce a novel data center design based on emerging 60 GHz RF technology that uses wires only to deliver power to its server nodes. Fundamental limitation of wireless data centers is that the maximum number of live connections in the network is directly proportional to the full volume occupied by the data center divided by the radiating volume of a single antenna beam. Consequently, we integrate wireless transceivers and switching logic within each server node and collocate them in cylindric racks to establish a semi-regular mesh topology. Our exploration of the resulting design space shows that while attaining comparable bandwidth, our wireless data center exhibits substantially higher fault tolerance, improved latency, lower power consumption, and easier maintenance than a conventional wired data center.

“…Ultra-high data rate short-range radio modules for multimedia applications operating in the 60-GHz band have been greatly considered in the last few years [1][2][3][4]. Although mm-wave ICs have traditionally been domain of GaAs, InP, and pHEMT technologies, the continuous scaling of silicon processes has made sub-lm CMOS technologies valuable candidates to cover mm-wave applications, thus allowing integration of analog and digital parts in a single chip and reducing cost [1,2].…”

An amplifier topology based on a transformercoupled cascode stage is presented and compared with the most used solutions for sub-lm CMOS power amplifiers, which are the common-source stage, cascode stage, and capacitive-coupled cascode stage. The comparison was carried out by designing each amplifier in a 65-nm CMOS technology and for a 60-GHz operating frequency. The design was optimized for a trade off among power gain, saturated output power, and linearity. Operating from a 1.2-V supply voltage, the proposed amplifier improves both small-signal and large-signal performance with respect to the most common approaches, thus demonstrating effectiveness with sub-lm CMOS technologies and mm-wave operation.
