Full textPortable communication systems require, in part, high-efficiency radio frequency power amplifiers (RF PA) if battery lifetime is to be conserved. Conventional amplifier classifications and definitions are presented in a unified and concise format. The Bipolar Junction Transistor (BJT) and Metal-Semiconductor Field Effect Transistor (MESFET) are evaluated as active devices in high-efficiency RF PA designs. Two amplifier classes (class CE and class F) meet the system requirements of an 850 MHz operating frequency, a power output of 3 W, a battery supply voltage of 9 Vdc, and a sinusoidal-type signal to be amplified. Both classes are evaluated through recent research literature and simulated using the PSpice® computer simulation program. Class CE and class F are found to provide efficiencies exceeding 80 percent under the given system constraints.Master of Science

Full textDenna avhandling behandlar ett antal aspekter av digital beteendemodellering och korrektion av effektförstärkare för radiofrekvensapplikationer. När prestandan hos en beteendemodell skall bedömas är det för det första viktigt att ha ett utvärderingskriterium och för det andra är det viktigt att detta kriterium fokuserar på de relevanta delarna av beteendet man är intresserad av. Detta används i kriteriet weighted error spectral power ratio (WESPR) genom att en viktning införs. Denna viktning används för att fokusera på de aspekter av beteendet som är viktiga att beskriva. På samma sätt är det viktigt att fokusera på att minimera de relevanta delarna av modellfelet. Genom att använda viktningen från WESPR när parametrarna i beteendemodellen skall estimeras visas det på två olika typer av PA att modellprestandan kan förbättras och modellkomplexiteten reduceras när ett relevant felkriterium används. När en modell av ett system byggs är det fördelaktigt att använda den kunskap man har om det fysikaliska systemet. Det kan förbättra modellprestandan samtidigt som antalet parametrar kan reduceras. Genom att börja med en fysikaliskt motiverad modell av en effektförstärkare och införa antaganden härleds de populära minnespolynomen. Dessa har tidigare inte haft någon fysikalisk förklaring. Dessutom härleds tre nya minnespolynom. Av dessa visar två av strukturerna lägre modellfel samtidigt som färre parametrar används än i de tidigare publicerade minnespolynomen. Metoder för att förbättra energieffektiviteten och linjariteten i effektförstärkare har undersökts. En av dessa metoder är digital predistorsion (DPD) vilken förbättrar linjariteten och möjliggör på så vis högre uteffekter, vilket i sin tur förbättrar energieffektiviteten. Den andra testade metoden går ut på att förändra signalen genom att reducera effekttopparna så att signalen blir lämpligare för förstärkaren. Det visas experimentellt att kombinationen av dessa metoder kan resultera i förbättringar av energieffektiviteten på 2-4 gånger. En instabilitet i återkopplingsslingan för parameteruppdateringen av DPD identifieras och två förslag på lösningar ges. Det första förslaget modifierar parametrarna så att instabiliteten undviks. Det andra förslaget förändrar signalen så att de höga amplituderna undviks och systemet stabiliseras på detta sätt. Slutligen studeras de ickelinjära effekterna i klass-D utfasningsförstärkare. Tre modellstrukturer föreslås och utvärderas på uppmätta data från två olika förstärkare. För att reducera störningarna i utsignalen från förstärkarna föreslås en DPD-algoritm som använder signaler med konstant amplitud (rent fasmodulerade signaler). Denna DPD utvärderas och det visas att den kan reducera störningar i utsignalen hos en modern 32 dBm klass-D utfasande förstärkare så att den uppfyller linjaritetskraven för signaler som används i nedlänken (från basstation till mobil enhet) i telekommunikationssystemet universal mobile telecommunications system (UMTS).

Full textIn all radio frequency (RF) electronic communication systems, power amplifiers (PAs) are used to generate the final transmitted signal. Specifically, these PAs are used to increase the output power of the transmitted signal. The PA accomplishes this by converting the applied direct current (DC) power to the PA into RF power, while being driven by a RF input signal. The portion of DC power that is not converted into RF power is dissipated as heat. The power conversion mechanism that takes place in a PA is described by the power conversion efficiency (PE) and the power added efficiency (PAE). A CubeSat is a small satellite in the shape of a 10 × 10 × 10 cm cube, weighing less than 1 kg and contains a RF electronic communication system which allows communication with the satellite. A CubeSat requires a PA with high PE in order to increase the lifetime of the on-board battery, facilitate thermal management on-board the satellite, increase system reliability, and reduce the size and manufacturing cost of the satellite. To maximize the theoretical PE of a RF PA, several design techniques and classes of operation were investigated, the basis of which lies in the fulfilment of the necessary and sufficient conditions for a maximum PE. A PA, which uses the Class-F-1 (inverse Class-F) mode of operation, fulfils the necessary and sufficient conditions for a maximum theoretical PE, and therefore presents itself as a good option for a high efficiency PA. This thesis presents the design of a Class-F-1 PA, using the Cree CGH40010F GaN power active device. An optimum output matching network is used to terminate the drain of the GaN power active device with the required load impedances at the fundamental, 2nd and 3rd harmonic frequencies of operation. The designed PA delivers a maximum PE of 95 % at an operating frequency of 2.2 GHz, a maximum PAE of 82 % at an operating frequency of 2.2 GHz and a maximum output power of 40.6 dBm at an operating frequency of 2.2 GHz.
