This paper presents the differential LNA design for unlicensed 60 GHz band. The architecture is elaborated in conjunction with process-related effects (ground slits) in order to minimize the modeling errors and enhance the performance. The differential test LNA is fabricated in IHP SG25H1 high performance 0.25 um BiCMOS SiGe:C technology. On wafer measurement results have shown the gain of 24.5 dB with more than 10 GHz operational bandwidth. Power consumption of less than 60 mW is observed. Average in-band noise figure of 5.95 dB with a minimum of 5.3 dB was measured.

Today, more than ever, the public demands credible and understandable information about the quality of the environment in which they live or work. However, the environmental parameters monitored by commercial sensors do not give information about pollutants presence but about general state of our surroundings. Accordingly, innovative and multidisciplinary methods are needed to carry out efficient information exchange across the various sectors involved in environmental monitoring. The SENSEIVER (SENSor/transcEIVER) proposal presents a joint effort to reinforce the relevant technical bases by providing excellent training opportunities to young researchers in the following fields: (1) innovative and cost-effective sensors and their fabrication in LTCC (Low-Temperature Co-fired Ceramics) technology, (2) new sensitive materials as coating layers for unique LTCC microsensors platforms, (3) highly energy-efficient UWB (ultra wideband) transceivers compatible with designed LTCC sensors, and (4) intelligent systems for acquisition, processing and displaying data relevant to soil, air and water quality. ITN is composed of five outstanding academic/research participants, three leading industrial partners (SMEs) and three associated partners, from six countries. This training network has significant potential to improve career perspectives of 19 early-stage and 6 experienced researchers from partnering institutions and to spread expertise, knowledge and skills to wider scientific, engineering and environmental communities. Moreover, this ITN will expose all participants to complementary schools of thought that will initiate research in new areas and new topics within curriculum, giving it fresh perspective to the market oriented applications of designed materials, sensors and transceivers.

Small Cells, Cloud-Radio Access Networks (C-RAN), Software Defined Networks (SDN) and Network Function Virtualization (NVF) are key enablers to address the demand for broadband connectivity with low cost and flexible implementations. Small Cells, in conjunction with C-RAN, SDN, NVF pose very stringent requirements on the transport network. Here flexible wireless solutions are required for dynamic backhaul and fronthaul architectures alongside very high capacity optical interconnects. However, there is no consensus on how both technologies can be most efficiently combined. 5G-XHaul proposes a converged optical and wireless network solution able to flexibly connect Small Cells to the core network. Exploiting user mobility, our solution allows the dynamic allocation of network resources to predicted and actual hotspots. To support these novel concepts, we will develop: 1) Dynamically programmable, high capacity, low latency, point-to-multipoint mm-Wave transceivers, cooperating with sub-6-GHz systems; 2) A Time Shared Optical Network offering elastic and fine granular bandwidth allocation, cooperating with advanced passive optical networks; 3) A software-defined cognitive control plane, able to forecast traffic demand in time and space, and the ability to reconfigure network components. The well balanced 5G-XHaul consortium of industrial and research partners with unique expertise and skills across the constituent domains of communication systems and networks will create impact through: a) Developing novel converged optical/wireless architectures and network management algorithms for mobile scenarios; b) Introduce advanced mm-Wave and optical transceivers and control functions; c) Support the development of international standards through technical and techno-economic contributions. 5G-XHaul technologies will be integrated in a city-wide testbed in Bristol (UK). This will uniquely support the evaluation of novel optical and wireless elements and end-to-end performance.

This paper describes the design and optimization of a Chebyshev 5th order low pass filter with included circuit for automatic process calibration and compensation. The filter is realized using lumped elements in 130 nm radio frequency (RF) CMOS process and is dedicated to cover lower sub-band (3.4 GHz - 4.8 GHz) of ultra-wideband (UWB) system. The proposed full on-chip calibration concept estimates MIM-Capacitor (Metal-Insulator-Metal) capacitance process-induced variation against more stable on-chip MOS capacitor reference. In order to estimate the capacitance value, a low frequency oscillator is designed, which uses both types of capacitors for generating the oscillations, one after another. The MIM capacitor value is determined in digital domain based on the ratio of two oscillation frequencies and its exact needed value is obtained using a compensation capacitor bank. Detailed mathematical optimization of the calibration method is presented. All RF, analog and digital circuits have been integrated on a test chip and fabricated in 130 nm RF CMOS process. The produced ICs have been on-wafer measured and compared to simulation results. According to obtained results, the proposed calibration concept lowers process-induced filter transfer characteristic variation from approximately 5 dB to 0.6 dB at the critical frequency. The calibration needs to be applied just once at the beginning of circuit operation. The total area of implemented calibration circuit is less than 0.1 mm2. The same method and the compensation circuit can be employed for the calibration of all on-chip circuits whose performance is affected by MIM capacitance process variation. © MIDEM Society.

Key objectives of EUWB are i) to explore the enormous economic potential of the ground-breaking Ultra-Wideband (UWB) radio technology, ii) to extend the UWB concept with advanced cognitive radio, multiband/multimode networking, and multiple antenna system concepts, iii) to enable the introduction of advanced services and competitive applications using the radio spectrum in a sophisticated manner.\nThe advanced scientific and technical project work will be accompanied by activities in European and world wide regulation and standardisation bodies in which EUWB partners are highly committed. As a key for economic success of UWB, the project partners will continue to devote significant efforts to participation in CEPT ECC, IEEE, ITU, ETSI, and ECMA working towards consensus building and iterative improvement of the initial European and world-wide UWB regulation and standardisation.\nUWB technology enables gigabits per second short range communications and inherent precise real-time location tracking. Prominent examples to be implemented in the EUWB project are the Intelligent Home environment, the Public Transport environment, the Automotive environment and the Next Generation of Heterogeneous Public Access Network environment, following a strong demand from the mentioned industry sectors.\nEUWB is an industry-led initiative of 22 highly regarded industrial, consulting, and academic organisations. It builds on previous projects, such as PULSERS, and take into account stakeholders of the whole value chain. Major aim is to consolidate the technology advances in scientific areas related to UWB and to define system concepts for the envisaged four application areas. The results will be materialised in four application platforms built on the open UWB technology developed in EUWB. Besides integration in the AIRBUS plane, the DAIMLER car, the PHILIPS future home, and the TELEFNICA access network, scientific studies will guide industry to gain competitiveness with their UWB system.

Application demands for several gigabits per second data throughput could be fulfilled using available unlicensed 60GHz band. There are several standardization activities that define systems for such tasks with channel bandwidth of at least 2GHz. Here we present several solutions for 60GHz antenna components based on linearly polarized (dipole) element. The four antennas presented have one dimensional or two dimensional configurations that result in desired radiation pattern and maximal gain. Initial measurement of prototypes show satisfactory results and proof the concept. Copyright © 2010 The authors.
