Available in PDF, EPUB and Kindle. Book excerpt: The ultimate objective is to create a system design of a low noise amplifier that can function at a frequency of 24GHz. The basic and very important application of the low noise amplifier is in receiver models. Low noise amplifiers are used on a large scale in all most all types of receivers and as a single transistor can have multiple receivers, it is very obvious that the design of low noise amplifiers is important and on a large scale when compared with any other type of transistors. The amplifier design has to be a multistage design, i.e. it has more than one transistor. The multistage low noise amplifier is to be designed using the transistor MGF4961BL. The transistor is a super low noise HEMT. As the name suggests the basic agenda in designing this type of amplifier is to provide low noise amplification at 24GHz. The Noise figure allowed of should be less than 1 dB and the total output gain should be 25dB overall. The overall gain of 25dB is needed. The number of stages in an amplifier design depends on the gain that a single transistor that can provide depending upon its S-parameters. The matching networks is to be designed and aligned using proper Zin so that there is no mismatch and hence no dropping of the gain.

Available in PDF, EPUB and Kindle. Book excerpt: There is a continuous demand for the improved performance of low noise amplifiers in modern and future applications. Radar sensors are employed in automotive detection systems to provide early detection of hazards on the road. Radar sensors for automotive detection systems can be expected to operate at the 24 GHz band range. Since most telecommunication systems require low noise amplifiers in their receivers, it is essential to understand and appreciate the design of low noise amplifiers at microwave frequencies. In addition, low noise amplifiers are expected to provide sufficient power gain to the overall system. Gains ranging from 10 dB to 40 dB are often required by devices including smart phones, antennas, and phase-array radar systems. The amplifier should be able to provide the necessary gain for proper operation of the system. Finally, the low noise amplifier should be able to provide the necessary gain while ensuring minimal noise. Noise causes disturbances in the output signal thereby degrading the performance of the system. Noise can cause random humming noises in audio equipment, unexpected voltage drops, and equipment failure. Noise can be generated within electrical components caused from the vibration of charges. Therefore, the low noise amplifier should be designed to provide minimal noise. A multistage amplifier will be designed to operate at 24 GHz. Designing a 24 GHz low noise amplifier will provide ample preparation for designing low noise amplifiers for radar sensors. The low noise amplifier will also achieve a noise figure less than 1.7 dB and a gain of at least 37 dB. Such noise and gain levels are common requirements of low noise amplifiers in modern devices. Empirical formulas and Smith charts are utilized to obtain essential parameters of the low noise amplifier. Simulation tools such as RF Microwave E-Book, Matlab, and Microwave Office were used to verify and analyze the performance of the multistage amplifier. The three-stage low noise amplifier achieved a noise figure of 1.539 dB and a gain of 39.75 dB meeting the design parameters required for use in low noise high frequency systems. The design parameters are summarized below. Frequency of operation = 24 GHz Achieve a noise figure no greater than 1.7 dB Achieve an overall gain of at least 37 dB

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.

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.

Download or read book Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation written by Federico Bruccoleri and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low Noise Amplifiers (LNAs) are commonly used to amplify signals that are too weak for direct processing for example in radio or cable receivers. Traditionally, low noise amplifiers are implemented via tuned amplifiers, exploiting inductors and capacitors in resonating LC-circuits. This can render very low noise but only in a relatively narrow frequency band close to resonance. There is a clear trend to use more bandwidth for communication, both via cables (e.g. cable TV, internet) and wireless links (e.g. satellite links and Ultra Wideband Band). Hence wideband low-noise amplifier techniques are very much needed. Wideband Low Noise Amplifiers Exploiting Thermal Noise Cancellation explores techniques to realize wideband amplifiers, capable of impedance matching and still achieving a low noise figure well below 3dB. This can be achieved with a new noise cancelling technique as described in this book. By using this technique, the thermal noise of the input transistor of the LNA can be cancelled while the wanted signal is amplified! The book gives a detailed analysis of this technique and presents several new amplifier circuits. This book is directly relevant for IC designers and researchers working on integrated transceivers. Although the focus is on CMOS circuits, the techniques can just as well be applied to other IC technologies, e.g. bipolar and GaAs, and even in discrete component technologies.
