Book excerpt: The outstanding characteristic of the maser as a microwave amplifier is its inherently low noise. The measurable noise temperature of 10-20K indicates that the maser is operating at the theoretical limit of 1-2K. With no restrictions on the magnet size there appears to be no limit to the operating frequency range. Potential power handling capabilities of milliwatts tuned over hundreds of megacycles should make this an ultimate low-noise amplifier. Both the pulsed and multi-level continuous systems will be greatly improved thru the use of new maser materials. The P/N function parametric amplifiers requiring little or no cooling and no magnetic field have shown almost comparable performance below 1000 Mc. For frequencies above 6-7 KMc, however, the design of the functions will have to be vastly improved. Ultimately, the limit will be set by the incompatibility between the barrier capacitance and the spreading resistance both of which should be minimal for increasing figure of merit. The garets and ferrites may then play an intermediate role in spite of the relatively large pumping powers, since there appears to be no frequency limitation and extreme cooling is not required. In all types of operation the use of traveling wave structures is expected to allow markedly improved performance. The parametric beam tubes, electron beams with mixed properties and the improved low noise conventional TW and BW tubes should find rapid acceptance if the low noise features can be scaled to the higher frequencies.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the first standalone book that combines research into low-noise amplifiers (LNAs) with research into millimeter-wave circuits. In compiling this book, the authors have set two research objectives. The first is to bring together the research context behind millimeter-wave circuit operation and the theory of low-noise amplification. The second is to present new research in this multi-disciplinary field by dividing the common LNA configurations and typical specifications into subsystems, which are then optimized separately to suggest improvements in the current state-of-the-art designs. To achieve the second research objective, the state-of-the-art LNA configurations are discussed and the weaknesses of state-of the art configurations are considered, thus identifying research gaps. Such research gaps, among others, point towards optimization – at a systems and microelectronics level. Optimization topics include the influence of short wavelength, layout and crosstalk on LNA performance. Advanced fabrication technologies used to decrease the parasitics of passive and active devices are also explored, together with packaging technologies such as silicon-on-chip and silicon-on-package, which are proposed as alternatives to traditional IC implementation. This research outcome builds through innovation. Innovative ideas for LNA construction are explored, and alternative design methodologies are deployed, including LNA/antenna co-design or utilization of the electronic design automation in the research flow. The book also offers the authors’ proposal for streamlined automated LNA design flow, which focuses on LNA as a collection of highly optimized subsystems.

Download or read book Low Noise Microwave Amplifier at 23 GHz written by Lovepreet Singh Josan and published by . This book was released on 2019 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Three-Stage Low Noise Microwave Amplifier is designed at a frequency of 23 GHz where the design will provide a Gain ≥ 30 dB and NF ≤ 1.8 dB. The transistor selected for this project is MGF49641B by Mitsubishi Electric. This transistor is a High Electron Mobility Transistor (a super low noise GaAs transistor) and has a high gain and a very low noise figure at higher frequencies. Additionally, LNA's provide a high gain and henceforth they are used in various industrial and military applications. An LNA provides the needed gain while keeping the noise as minimum as possible. In this project, a highly desired configuration using balanced shunt stubs is utilized such that it provides a better VSWR, gain, and noise figure. The software programs that are used in this project are Microwave office (AWR environment) for designing of the Amplifier, MATLAB for the coding and verification and RF/MW Design software by Dr. Matthew M. Radmanesh to verify the calculations.

Available in PDF, EPUB and Kindle. Book excerpt: Broadband RF and Microwave Amplifiers provides extensive coverage of broadband radio frequency (RF) and microwave power amplifier design, including well-known historical and recent novel schematic configurations, theoretical approaches, circuit simulation results, and practical implementation strategies. The text begins by introducing two-port networks to illustrate the behavior of linear and nonlinear circuits, explaining the basic principles of power amplifier design, and discussing impedance matching and broadband power amplifier design using lumped and distributed parameters. The book then: Shows how dissipative or lossy gain-compensation-matching circuits can offer an important trade-off between power gain, reflection coefficient, and operating frequency bandwidth Describes the design of broadband RF and microwave amplifiers using real frequency techniques (RFTs), supplying numerous examples based on the MATLAB® programming process Examines Class-E power amplifiers, Doherty amplifiers, low-noise amplifiers, microwave gallium arsenide field-effect transistor (GaAs FET)-distributed amplifiers, and complementary metal-oxide semiconductor (CMOS) amplifiers for ultra-wideband (UWB) applications Broadband RF and Microwave Amplifiers combines theoretical analysis with practical design to create a solid foundation for innovative ideas and circuit design techniques.

Download or read book Design of a Three Stage Microwave Low Noise Amplifier at 10Ghz written by Shrey Singla and published by . This book was released on 2012 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project consists of a X-band three-stage Low noise amplifier (LNA). I used components from vendors like Murata, Mini-circuits, Anadigics and NEC to create and simulate the design. Agilent's ADS was used in the design simulation and completion. The LNA is required to provide a 30 dB gain and an overall noise figure of 2 dB at a frequency of 10 GHz. The actual design provides an overall 40.01 dB gain over 10 percent bandwidth and a 0.471 dB of noise figure. The LNA designed meets and exceeds our design requirements. Advancements and the end user requirements also influence these limits and pushing them to a new level. Thus, this LNA design serves as to meet that fast growing market and serve as a baseline for future projects. This project provides a solid base and practicable hands-on experience with industrial standard advanced tools. It also provides an overview of types of amplifiers, detailed design steps and types of matching techniques. Along with this, the analysis of various design factors effecting the performance of the final LNA such as VSWR, isolation and stabilization are also performed.
