Research ArticleOpen accessIn the keywordsA 2-12 GHz Low Noise Amplifier Design for Ultra Wide Band ApplicationsV. Vaithianathan, J. Raja, R. SrinivasanProblem statement: The Low Noise Amplifier (LNA) is a core block of an Ultra Wide Band (UWB) receiver since it amplifies a very weak signal received at the antenna to acceptable levels while introducing less self-generated noise and distortions. The LNA design poses a unique challenge as it requires simultaneous optimization of various performance parameters like power gain, input matching, … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 9 Jun 2012 · 7,397 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDesign of A Microwave Amplifier for Wireless ApplicationM. Habib Ullah, Badariah Bais, Norbahiah Misran et al.Problem statement: Low-Noise Amplifiers (LNA) are very indispensable components in the design of numerous types of communication receivers employed in microwave technology.

Research ArticleOpen accessIn the abstractGPS Ionospheric Total Electron Content and Scintillation Measurements during the October 2003 Magnetic StormMohammad Awad Momani, Takialddin A. Al Smadi, Farouq M. Al Taweel, Khaldoon A. GhaidanProblem Statement: Ionospheric scintillations, cause significant effects on satellite signals for communication and navigation in equatorial region and polar regions mainly during sever magnetic storms periods. This phenomenon is not fully understood due to few studies performed. The study investigates variability of Total Electron Content (TEC) and ionospheric scintillation during October 2003 magnetic storm over Antarctica using ground based GPS … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,508 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Fully Integrated Dual-Band Low Noise Amplifier for IEEE 802.11 and Hiper LAN ApplicationMow Shouxian, Ma Jianguo, Yeo Kiat Seng, Do Manh AnhA fully-integrated dual-band Low Noise Amplifier (LNA), which can be used for IEEE 802.11 and Hiper LAN applications, was investigated in this paper. The proposed LAN was implemented entirely pm a single chip based on a standard 0.18 μm 1P6M CMOS process. It draws 13 mA current from a 1.5-V voltage supply and achieves power gains of 17 and 10 … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,288 accessesView PDF Cite
