Available in PDF, EPUB and Kindle. Book excerpt: This report is about the design of a Ku-band two-stage low noise amplifier working at an operating frequency of 18 GHz. The specification of this low noise amplifier includes a gain, which is greater than 25dB and a low noise figure less than 1dB. The transistor used to design is ATF-36077 manufactured by Hewlett-Packard which is an ultra-low noise transistor providing a high and stable gain at the required frequency along with a low noise figure. The results obtained after running the simulations concluded that the two-stage low noise amplifier satisfactorily provided a power gain of about 24.7 dB and a low noise figure of about 0.68dB. As a result, cascading the two-stages consisting first stage as a minimum noise amplifier (MNA) and second stage as a maximum gain amplifier (MGA) helped us to achieve the specified requirements. The minimum noise amplifier stage helped us to reduce the noise at the input while the maximum gain amplifier stage helped us increase the gain. The matching networks at input and output terminals helped in achieving gain stability at the output. The schematic was implemented using the Agilent's Advanced Design System (ADS) software. The circuit simulation was carried out in the same software and the results were verified. The results were also verified using the hand calculations and MATLAB software. At the end, the final layout was designed and sketched.

Available in PDF, EPUB and Kindle. Book excerpt: In order to design an amplifier at a certain frequency, the gain and noise figure needs to be decided on the basis of the market research. After deciding these three values, a transistor was selected such that it helped to achieve these values. The formulas used in the design process determined the number of stages required to complete the design and to measure the performance of the amplifier. After reviewing more than fifty transistors, the transistor FHX13/14LG was decided for the design of Low Noise Amplifier in the Ku Band at 16 GHz. The design objective was to achieve 40 dB gain with a noise figure of less than 1dB at the specified frequency. After the preliminary calculations, it was concluded that there will be three stages based on the selected transistor. The finalization of each stage was a challenge because of the trade-off issues in gain and noise figure. In order to verify the results, National Instruments Microwave Office (student version) was used for simulation. It gave the simulation values which were very close to the hand calculations. This was also verified using MATLAB along-with an RF/MW E-Book Software* software developed by Dr. Matthew Radmanesh with his published book "Advanced RF & Microwave Circuit Design" for accuracy.

Book excerpt: Design of Three stage Ku band Low Noise Amplifier operating at 15 GHz By Praveen D'souza Master of Science in Electrical Engineering The main aim of this project is to simulate and design a three stage Ku band Low Noise Amplifier to find the gain and noise figure at 15GHz. In order to fulfil this requirement of high gain and low noise, a transistor MGF4965BM is chosen. This transistor belongs to Mitsubishi Electric Corporation and is basically a very low noise GaAs HEMT. It is desired to get a gain of more than 30dB with a low noise figure lower than 2dB. Microstrip lines are used to design the input and output matching networks to get the desired gain with low noise figure. The amplifier design must be a multistage design, i.e. it has more than single transistor. All the results were verified using hand calculations, MATLAB and RF and Microwave software. The three stage LNA design and simulation was done using Microwave AWR Office Software. Operating Frequency15GHz Total Gain> 30dB Total Noise Figure

Book excerpt: ABSTRACT THREE-STAGE LOW NOISE AMPLIFIER at 16GHz By Prashanth Hara Master of Science in Electrical Engineering The purpose of this project is to design a three stage LNA in which all the stages are identical in nature. The transistor used for the design is MGF 4937 - AM operating at a frequency of 16GHz with the goal of achieving a total gain over 30dB and a noise figure less than 2dB. The basic steps involved in the design are: 1) Choosing the appropriate transistor, 2) Conduting the stability test of the transistor, 3) Calculating the gain and noise figure of the amplifier and 4) Designing the input matching network , output matching network and the M-prime network. First the smith chart is used for developing the design and then the design is verified using Microwave Office. The hand calculations are also verified using Matlab and RF/MW design software. The final three-stage low noise amplifier design was simulated using Microwave Office software obtaining a gain of 33dB and a noise figure of 1.6dB.

Available in PDF, EPUB and Kindle. Book excerpt: Three Stage K-band low noise amplifier which is operating at a frequency of 20GHz. The specifications of this amplifier include gain that is greater than or equal to 40dB and a noise figure of less than 1dB. The transistor used for this project is MGF4964BL which is manufactured by Mitsubishi Electric. It is a super low noise GaAs HEMT (High Electron Mobility Transistor) transistor. It provides high gain and low noise figure for high frequency operations. The results are obtained using three different ways, namely, hand calculations, MATLAB and AWR (Microwave Office) simulation. Also, the values derived by hand calculations and MATLAB are verified using the Microsoft RF/MW Software, designed by Dr. Radmanesh. The Amplifier is designed using distributed elements for all three stages. All three stages of this amplifier are a low noise amplifier. It also includes an inter-stage matching network. Three stages provide the gain of 40.8dB and satisfies noise figure criteria too. The concept is using Low Noise Amplifier (LNA) for three stages is very simple. It makes calculations easy and when we add more LNA stages, it increases the gain by keeping noise figure less than 1dB. The schematic was designed by hand calculations whose values were verified twice. Once by using the Microsoft RF/MW Software and second time using MATLAB. The simulation was done after designing the inter-stage matching network on Microwave Office (AWR). First it was carried out for a single stage and then for all three stages together. The results were verified using graphs in AWR.
