Broadband amplifiers that can accommodate commercial communication standards such as GSM, UMTS, Wi-Fi, and Wi-Max are extremely important for radio equipment manufacturers. To achieve this coverage, the amplifier should provide high gain and efficiency over a band from 800 to 5200 MHz. Although there are transistor devices that have cut-off frequencies well over these frequencies, amplifiers covering such a broad-bandwidth are difficult to design due to the requirement of broadband matching networks. In this work, design of broadband tunable matching networks is investigated using Real Frequency Direct Computational Technique (RF-DCT). In order to be able to work on sample structures, impedance transforming filters are chosen and a broadband tunable matching network has been designed. Implementation of tunable inductors is investigated and the performance of a tunable matching network using tunable inductors and capacitors is demonstrated. Eventually a broadband frequency tunable amplifier has been designed using the tunable inductor concept. (c) 2013 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.

An Investigation of Link Quality Assessment for Mobile Multi-hop and Multi-rate Wireless Networks Zhou, Jinglong; Jacobsson, Martin; Onur, Ertan; Niemegeers, Ignas (Springer Science and Business Media LLC, 2012-07-01) Wireless ad hoc networks will be an important component in future communication systems. The performance of wireless ad hoc networks can be improved by link quality-aware applications. Wireless link quality is dynamic in nature, especially in mobile scenarios. Therefore, accurate and fast packet delivery ratio estimation is a prerequisite to good performance in mobile, multi-hop and multi-rate wireless ad hoc networks. In this paper, we propose a novel packet delivery ratio estimation method that improves t...
The performance and efficiency of envelope elimination and restoration transmitters for future multiple-input multiple-output wireless local area networks Nesimoglu, T.; Parker, S. C. J.; Morris, K. A.; McGeehan, J. P. (Institution of Engineering and Technology (IET), 2008-03-01) The inefficiency of contemporary power amplifiers ( PAs), when operating in their linear region, is a major obstacle to mobile operation of wireless local area networks ( WLANs) based on IEEE 802.11n. Therefore the use of more efficient envelope elimination and restoration ( EER) transmitter architectures is considered. In addition to high efficiency it is also necessary to satisfy the spectral mask and achieve satisfactory link- level performance. Link- level simulations of a contemporary WLAN PA show that...
Wireless Passive Sensor Networks Akan, Ozgur B.; Isik, M. Talha; Baykal, Buyurman (Institute of Electrical and Electronics Engineers (IEEE), 2009-08-01) The primary challenge in wireless sensor network deployment is the limited network lifetime due to finite-capacity batteries. Hence, the vast majority of research efforts thus far have focused on the development of energy-efficient communication and computing mechanisms for WSNs. In this article a fundamentally different approach and hence completely new WSN paradigm, the wireless passive sensor network, is introduced. The objective of the WPSN is to eliminate the limitation on system lifetime of the WSN. I...
Systematic message schedule construction for time-triggered CAN Schmidt, Klaus Verner; Schmidt, Şenan Ece (Institute of Electrical and Electronics Engineers (IEEE), 2007-11-01) The most widely used standard for in-vehicle communication networks that interconnect electronic control units is the controller area network (CAN). However, the event-triggered architecture of CAN introduces several issues, such as predictability, signal jitter, and reliability. Different time-triggered networks. are being developed to address these issues. In this paper, we focus on time-triggered CAN (TTCAN), which achieves time-triggered behavior by implementing time-division multiple access on the exis...
Impact of defected ground structures on the bandwidth of quarter wave impedance transformers and branch line hybrids Polater, Ahmet Mert; Nesimoglu, Tayfun (Wiley, 2016-05-01) In this article, impedance transformers and branch line hybrids are selected to demonstrate the impact of defected ground structures on the operational bandwidth of microwave circuits. Three different branch line hybrids are studied with simulations and laboratory measurements, these are; a standard branch line hybrid, one using tapered lines and another one using both tapered lines and DGS. Based on these results, an optimum design in terms of location, size and number of DGS was proposed to achieve the wi...
