Available in PDF, EPUB and Kindle. Book excerpt: The aim of the project is to design an RF-power amplifier using hybrid-900 couplers. The main objective of this project is designing the layout and simulation using advanced design system and RF/MW E-book software at an operating frequency of 12 GHz. A low noise transistor MESFET MGF1941AL was chosen to attain the power gain greater than or equal 10 dB and a 28 dBm of output power. To design the input and output matching networks lossless lumped elements were used since these components exhibit lower sensitivity as frequency changes. In addition, two hybrid-900 couplers were used to divide and combine the applied power. Hybrid-900 couplers were designed using microstrip line method on a RO4003C substrate (from Rogers Corporation). Every single design step was verified by the Advanced Design System (ADS) and RF/MW E-book.

Available in PDF, EPUB and Kindle. Book excerpt: Power amplifiers are at the heart of any high frequency communications network. Increasing the output power of amplifiers is conventionally carried out through 90-degree hybrids at frequencies above 3GHz and through 180-degree hybrids at lower frequencies. In this thesis, we go through the design, simulation, and prototype building and testing phases of a C-band, 47dBm solid-state microwave power amplifier and investigate its performance using the two types of hybrids. The device used is a Fujitsu device consisting of two independent transistors; each has a 10dB linear gain and a saturated output power of 44dBm. Three simulation packages were used in the design phase, ADS, a product of Hewlett-Packard, Zeland, a product of Zeland Software Inc, and Sonnet b, a product of Sonnet Software Inc. The results of tests revealed that, when a 180-degree hybrid was used, the amplifier exhibited better performance in terms of output power, power-added efficiency, and inter-modulation distortion. However, the amplifier utilizing a 90-degree hybrid exhibited better return loss results. The design, simulation, and testing of the amplifier were carried out at Fujitsu FCSI under the guidance and appreciated help of the applications lab engineering team.

Input and output matching networks using microstrip lines are then designed to meet the design specification. Finally, the entire design is put together and simulated to show the overall amplifier performance.

Download or read book High Performance Power Amplifiers Utilizing Novel Balun Design Techniques written by Alexander Nicholas Stameroff and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this PhD. research, a new power amplifier architecture is introduced. This work develops the push-pull architecture into a multifunctional matching network and combiner to create a high power, high efficiency, linear power amplifier (PA) that operates over a wide bandwidth. The traditional push-pull architecture uses an input balun to split a single ended signal into a differential signal, amplify it, and recombine it. This new technique realizes this architecture as a planar, hybrid, PA in X band. The first contribution of this work is the development of planar Marchand baluns that operate over a wide bandwidth. An analysis technique is developed and broadside coupled, Marchand baluns in an inhomogeneous medium are employed. These baluns operate over a bandwidth from 5 to 26 GHz with amplitude and phase imbalances less than 0.5 dB and 5°, respectively. The even and odd mode behavior of the Marchand balun is utilized to provide harmonic matching for the PA. The balun inherently presents an open circuit to common mode signals at its center frequency. This is utilized to match the second harmonic to an open circuit condition. A band-stop filter is used as a harmonic trap to match the third harmonic to a short circuit. This achieves inverse class F matching for high efficiency operation. This network simultaneously acts as a combiner and matching network for high power and efficiency. A prototype PA was fabricated to prove this concept and achieves a saturated output power, Psat, greater than 33 dBm and a power added efficiency, PAE, greater than 62% over the bandwidth from 9.7 to 10.3 GHz.This technique was refined to operate over a wide bandwidth. The harmonic trap was removed and the out-of-band behavior of the balun was used to provide the short circuit matching at the third harmonic. A prototype PA was fabricated that achieved a 1 dB compressed power, P1dB, and PAE greater than 40 dBm and 55% respectively over the band from 8 to 12 GHz. Finally, the technique was extended to combine power from four transistors by the development of a 4-to-1 balun. A prototype PA was fabricated to prove this concept and achieves a P1dB and PAE greater than 43 dBm and 55% over the band from 8 to 12 GHz.
