Novgorod, Russia; [email protected] * Correspondence: [email protected] Received: 14 January 2020; Accepted: 28 January 2020; Published: 3 February 2020 Abstract: The gyrotrons are powerful sources of coherent radiation that can operate in both pulsed and CW (continuous wave) regimes. Their recent advancement toward higher frequencies reached the terahertz (THz) region and opened the road to many new applications in the broad fields of high-power terahertz science and technologies. Among them are advanced spectroscopic techniques, most notably NMR-DNP (nuclear magnetic resonance with signal enhancement through dynamic nuclear polarization, ESR (electron spin resonance) spectroscopy, precise spectroscopy for measuring the HFS (hyperfine splitting) of positronium, etc. Other prominent applications include materials processing (e.g., thermal treatment as well as the sintering of advanced ceramics), remote detection of concealed radioactive materials, radars, and biological and medical research, just to name a few. Among prospective and emerging applications that utilize the gyrotrons as radiation sources are imaging and sensing for inspection and control in various technological processes (for example, food production, security, etc). -

Another approach is to Abstract— This paper presents a novel interconnect for use a separate transition [4] [5]. Using a separate transition is coupling Millimeter-wave (mmW) signals from integrated crucial from performance perspective, as coupling the RF circuits to air-filled waveguides. The proposed solution is realized through a slot antenna implemented in embedded Wafer Level signal directly to the MMIC from the waveguide causes Ball Grid Array (eWLB) process. The antenna radiates into a waveguide modes to leak into the circuit cavity and hence high-resistivity (HR) silicon taper perpendicular to its plane, affect performance. The drawback of this solution is that it which in turn radiates into an air-filled waveguide. The requires bondwire connections between the waveguide- interconnect achieves a measured average insertion loss of 3.4 dB transition and the MMIC. Using bondwires at frequencies over the frequency range 116-151 GHz. The proposed interconnect is generic and does not require any galvanic beyond 100 GHz requires special compensation techniques [6] contacts. The utilized eWLB packaging process is suitable for because of the high inductive behavior of bondwires at these low-cost high-volume production and allows heterogeneous frequencies. integration with other technologies. This work proposes a This work addresses mmW system integration challenges by straightforward cost-effective high-performance interconnect for utilizing eWLB packaging technology. eWLB packaging mmW integration and thus addressing one of the main challenges facing systems operating beyond 100 GHz. -
RTT TECHNOLOGY TOPIC January 2015 Defence Spectrum – the New Battleground?
RTT TECHNOLOGY TOPIC January 2015 Defence Spectrum – the new battleground? In this month’s technology topic we look at contemporary military radio developments, the integration of LTE user devices into defence communication systems, the relevance of military research to 5 G deployment efficiency and related spectral utilisation and regulatory issues. Defence communication systems are deployed across the whole radio spectrum from long wave to light. This includes mobile communication systems at VHF and UHF and L Band and S band, LEO, MEO and GSO satellite systems (VHF to E band) and mobile and fixed radar (VHF to E band). Legacy defence systems are being upgraded to provide additional functionality. This requires more rather than less spectrum. Increased radar resolution requires wider channel bandwidths; longer range requires more power and improved sensitivity. Improved sensitivity increases the risk of inter system interference. Emerging application requirements including unmanned aerial vehicles require a mix of additional terrestrial, satellite and radar bandwidth. These requirements are geographically and spectrally diverse rather than battlefield and spectrally specific. The assumption in many markets is that the defence industry will be willing and able to surrender spectrum for mobile broadband consumer and civilian use. The AWS 3 auction in the US is a contemporary example with a $5 billion transition budget to cover legacy military system decommissioning in the DOD coordination zone between 1755 and 1780 MHz This transition strategy assumes an increased use of LTE network hardware and user hardware in battlefield systems. While this might imply an opportunity for closer coordination and cooperation between the mobile broadband and defence community it seems likely that an increase in the amount of defence bandwidth needed to support a broadening range of RF dependent systems could be a problematic component in the global spectral allocation and auction process. -

ATHENA NGSO SATELLITE EXHIBIT 1 Technical Information To
REDACTED FOR PUBLIC INSPECTION ATHENA NGSO SATELLITE EXHIBIT 1 Technical Information to Supplement Form 442 and Application Narrative A.1 Scope and Purpose This exhibit supplements FCC Form 442 and contains the technical information referenced in the application narrative that is required by Parts 5 and 25 of the Commission’s rules. A.2 Radio Frequency Plan (§25.114(c)(4)) The Athena satellite will have two E-band uplinks and two E-band downlinks. The downlink emissions are nominally centered at 72 GHz and 75 GHz and the uplink emissions are nominally centered at 82 GHz and 85 GHz1. The bandwidth for both the uplinks and downlinks is 2.1852 GHz. The TT&C uplink will be conducted at 2082 MHz with an occupied bandwidth of 1.5 MHz. The TT&C downlink will be conducted at 8496.25 MHz with an occupied bandwidth of 2.3 MHz. Table A.2-1 shows the frequency ranges to be used by the Athena satellite. 1 There is the possibility that mild tuning may be performed from the planned 72, 75, 82 and 85 GHz centered carriers (e.g., 74.8 and 82.2 GHz may be used for example to mitigate any potential, mild “inter-channel interference” due to spectral regrowth issues and limited transmit- to-receive isolation). In addition, a limited number of tests, estimated at one to two dozen, may be performed with continuous wave (CW), unmodulated carriers as far out as the band edges (i.e., 71-76 GHz and 81-82 GHz) to measure the atmospheric attenuation characteristics. -

Terahertz Band: the Last Piece of RF Spectrum Puzzle for Communication Systems Hadeel Elayan, Osama Amin, Basem Shihada, Raed M
1 Terahertz Band: The Last Piece of RF Spectrum Puzzle for Communication Systems Hadeel Elayan, Osama Amin, Basem Shihada, Raed M. Shubair, and Mohamed-Slim Alouini Abstract—Ultra-high bandwidth, negligible latency and seamless communication for devices and applications are envisioned as major milestones that will revolutionize the way by which societies create, distribute and consume information. The remarkable expansion of wireless data traffic that we are witnessing recently has advocated the investigation of suitable regimes in the radio spectrum to satisfy users’ escalating requirements and allow the development and exploitation of both massive capacity and massive connectivity of heterogeneous infrastructures. To this end, the Terahertz (THz) frequency band (0.1-10 THz) has received noticeable attention in the research community as an ideal choice for scenarios involving high-speed transmission. Particularly, with the evolution of technologies and devices, advancements in THz communication is bridging the gap between the millimeter wave (mmW) and optical frequency ranges. Moreover, the IEEE 802.15 suite of standards has been issued to shape regulatory frameworks that will enable innovation and provide a complete solution that crosses between wired and wireless boundaries at 100 Gbps. Nonetheless, despite the expediting progress witnessed in THz Fig. 1. Wireless Roadmap Outlook up to the year 2035. wireless research, the THz band is still considered one of the least probed frequency bands. As such, in this work, we present an up-to-date review paper to analyze the fundamental elements I. INTRODUCTION and mechanisms associated with the THz system architecture. THz generation methods are first addressed by highlighting The race towards improving human life via developing the recent progress in the electronics, photonics as well as different technologies is witnessing a rapid pace in diverse plasmonics technology. -
