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.

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.

Book excerpt: Abstract DESIGN OF A THREE STAGE MICROWAVE LOW NOISE AMPLIFIER by Rahul Gaikwad Master of Science in Electrical Engineering The objective of this project is to design a three-stage low noise amplifier (LNA) for specific design conditions. The final design should meet the desired specifications in regards to overall gain, noise and the matching network at the required frequency range. The design begins with the appropriate selection of transistor, stability check, gain and then building the matching networks for each of the three stages. The overall design is obtained by cascading each stage and should meet the specifications of the design. Once this design procedure is completed by performing the hand calculations and by using the Smith chart design method, the design is then further verified by using a simulation software (ADS), which is used to validate the results obtained from hand calculations.

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: This project is to design a two stage microwave amplifier with an overall gain of 29 dB and an overall noise figure less than or equal to 1 dB. The two stage microwave amplifier design consists of a Minimum Noise Amplifier Stage (MNA) followed by a Maximum Gain Amplifier Stage (MGA). For the amplifier design, I have used the RFMW essentials software which is provided by my professor Matthew M. Radmanesh, which helps to calculate the baseline solution, which is later used to design the two stage amplifier. Along with that I have used Agilent Technologies 'Advanced Design System Software (ADS)' to design the amplifier and also to calculate the required values for impedance matching. I have performed the simulations for the two stage amplifier design. I have used the transistor NE 3210S01 from NEC vendor for the two stage amplifier design. After transistor selection, I have calculated the DC biasing circuit for the two stage amplifier design. Then each stage is calculated using the ADS software and the results are displayed in the report individually for minimum noise stage and maximum gain stage. Then I have cascaded the two circuits and have achieved the overall gain of the project as 28.3dB and an overall noise figure of 0.8dB. Along with that VSWR, overall noise, S-parameter sweep and power gain simulation results of two stage amplifier design is simulated.

Noise modeling is approached from a well-established standpoint, based on the extraction of a small-signal equivalent circuit model; but also source pull-based techniques—both standard and advanced ones—are broadly illustrated. Finally, a comprehensive discussion on design of single- and multistage low-noise amplifiers is proposed, ranging from the most classical tools and methodologies, such as constant-gain and constant-noise circles, to novel graphical tools and more advanced concepts, such as global mismatch limits and noise measure.
