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: A Ku band multistage low noise amplifier also known as LNA was designed to operate at 16 GHz used mostly in radar applications. The LNA is required to provide a gain greater than 20dB and an overall noise figure of less than 2dB. NEC transistor NE321000, a heterojunction FET was selected for this design because it offered excellent gain and noise figure parameters at our required frequency. Simulations showed that the LNA provides a gain of 26 dB over a 10% bandwidth and a noise figure of 1.1dB. Thus, the LNA design met and exceeded our design requirements. It was determined by analysis that the first stage had to be designed as minimum noise and the other two stages as maximum gain to meet our overall noise and gain requirements. The input matching network, the output matching network and inter-stage matching networks were designed afterwards. The circuit schematic, layout and circuit test bench simulations were done using Agilent ADS. Stability, noise figure calculations and gain calculation were done manually as well as using ADS.

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.

Download or read book LOW NOISE MICROWAVE AMPLIFICATION written by A. W. Nagy and published by . This book was released on 1959 with total page 75 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Frequency-reconfigurable amplifiers have become a topic of interest because of the need for compact, light-weight and inexpensive communication systems able to operate at different frequency bands. Key subsystems in reconfigurable receivers and transmitters are the microwave amplifiers, either low-noise amplifiers (LNA) or solidstate power amplifiers (SSPA). Different topologies have been proposed in the last years and a big research effort has been devoted to reconfigurable components, such as RF-MEMS switches. The subject of study of this project is the design of a frequency-switchable microwave amplifier that can be operated at three different frequencies (3.2 GHz, 4 GHz and 4.8 GHz) in the 5G band. To this end, a systematic design procedure to obtain a balanced gain, noise figure and input return loss in the three bands, is proposed. This procedure is applied to an amplifier topology composed of a fixed input matching network (IMN) and a switchable output matching network (OMN). The IMN is based on a simple line-stub structure, and the OMN consists of a line-stub-line-stub structure in which the two stub lengths are selected using one SPDT switch connected to each stub. The amplifier behaviour is simulated using circuit and 2.5D electromagnetic simulations and optimized. The amplifier was fabricated on a conventional microwave substrate, and its S parameters and noise figure were measured and compared to simulations, showing a very good agreement, thus validating the design approach.

Each subsequent chapter introduces a new type of amplifier or circuit design, reviews its design problems, and explains how the RFT can be adapted to solve these problems. The authors take a practical approach by summarizing the design steps and giving numerous examples of amplifier realizations and measured responses. Provides a complete description of the RFT as it is first used to design multistage lumped amplifiers using a progressive optimization of the equalizers, leading to a small number of parameters to optimize simultaneously Presents modifications to the RFT to design trans-impedance microwave amplifiers that are used for photodiodes acting as high impedance current sources Discusses the methods using the RFT to optimize equalizers made of lossy distributed networks Covers methods and examples for designing standard linear multi-stage power amplifiers and those using arborescent structures Describes how to use the RFT to design multi ]stage active filters Shows the flexibility of the RFT to solve a variety of microwave circuit design problems like the problem of passive equalizer design for Radar receivers Examines a possible method for the synthesis of microwave antennas using the RFT Microwave Amplifier and Active Circuit Design Using the Real Frequency Technique is intended for researchers and RF and microwave engineers but is also suitable for advanced graduate students in circuit design.
