“…For instance, Fig. 31 shows a traveling-wave three-stage GaN amplifier presented by Quinstar in [167] achieves more than 33 dBm power and at least 16 dB gain from 75 to 100 GHz. On the other hand, in [168], a broadband radial stub is deployed in a W-band PA using a 100 nm Fraunhofer IAF GaN HEMT process to cover the completed W-band from 70 to 110 GHz.…”

This paper reviews the state-of-the-art of millimeterwave power amplifiers, focussing on broadband design techniques. An overview of the main solid-state technologies is provided, including Si, GaAs, GaN and other III-V materials, and both field-effect and bipolar transistors. The most popular broadband design techniques are introduced, before critically comparing through the most relevant design examples found in the scientific literature. Given the wide breadth of applications that are foreseen to exploit the millimeter-wave (mm-wave) spectrum, this contribution will represent a valuable guide for designers who need a single reference before adventuring in the challenging task of mm-wave power amplifier design. Index Terms-Broadband, millimeter wave, power amplifiers. I. INTRODUCTION T HE millimeter-wave (mm-wave) spectrum is attracting a great interest for applications such as 5G and future satellite communications that go well beyond the traditional niche of military and scientific use in terms of investments and potential revenues. The most attractive feature of mm-waves compared to the RF and microwave band is the huge spectrum availability that gives a great advantage in terms of capacity for telecommunication systems. Other advantages of mm-wave systems are the compact size of circuits, especially antennas, and the intrinsic easiness of frequency reuse thanks to the high free-space attenuations. There are also some advantages that are band-specific; for example, the very high attenuation in the 60 GHz band due to oxygen absorption that enables intrinsically secure communications. On the other hand, the very high frequency of operation poses significant challenges to system and circuit design. Similarly to what happens at lower frequency, one of the most critical circuit components is the power amplifier (PA). Its

“…State of the art high power solid-state MMIC processes could provide power amplifiers with saturated power in the range of 30dBm [5] [6]. On the contrary, no amplifier with a saturated power level in the range of 40W and sufficient bandwidth is available today for wireless communication systems at millimeter waves.…”

“…The availability of electronic devices at W-band (92 -95 GHz) is still limited. GaN SSPAs are recently presented with output power in the range of 1 W [8,9]. This power level is not sufficient for enabling the coverage of wide area corresponding to a sector with a wide angle, as required in the three tiers architecture (Fig.…”

Abstract-The European Horizon 2020 project TWEETHER aims to make a breakthrough in wireless networks to overcome the congestion of the actual mobile networks and foster the new 5G networks. A European Consortium including four universities and five companies from four European countries is devoting a relevant effort to realize novel terminals and transmission hubs to operate in the W-band (93 -95 GHz). This paper will describe the advancement of the project.
