2. 1. Integrated Antennas : Monolithic and Hybrid Approaches

   Author : Erik Öjefors; Anders Rydberg; Sayan Mukherjee; Duixian Liu; Uppsala universitet; []
   Keywords : Electronics; antenna travelling wave arrays; antenna phased arrays; phase shifters; micromachining; silicon; monolithic microwave integrated circuits; dipole antennas; loop antennas; slot antennas; Elektronik;

   Abstract : This thesis considers integration of antennas and active electronics manufactured on the same substrate. The main topic is on-chip antennas for commercial silicon processes, but hybrid integration using printed circuit board technology is also addressed. READ MORE

4. 2. Graphene FETs in Microwave Applications

   Author : Omid Habibpour; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microwave amplifiers; S-parameters characterisation; device modelling; MMIC; device fabrication; Graphene; subharmonic resistive mixers; integrated circuits; harmonic balance analysis; microwave FETs;

   Abstract : Graphene is a one-atom-thick sheet of carbon with numerous impressive properties. It is a promising material for future high-speed nanoelectronics due to its intrinsic superior carrier mobility and very high saturation velocity. READ MORE

5. 3. Tuneable Recursive Active Monolithic Microwave Integrated Circuit Filters

   Author : Robert Malmqvist; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In this thesis tuneable recursive active monolithic microwave integrated circuit (MMIC) filters are studied theoretically and experimentally. A possible future application for such filters is, for example, the microwave receivers of adaptive radar antennas. READ MORE

6. 4. Microwave CMOS VCOs and Front-Ends - using integrated passives on-chip and on-carrier

   Author : Markus Törmänen; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VCO; mixer; microwave; LNA; CMOS; front-end; System-on-Package;

   Abstract : The increasing demand for high data rates in wireless communication systems is increasing the requirements on the transceiver front-ends, as they are pushed to utilize more and wider bands at higher frequencies. The work in this thesis is focused on receiver front-ends composed of Low Noise Amplifiers (LNAs), Mixers, and Voltage Controlled Oscillators (VCOs) operating at microwave frequencies. READ MORE

7. 5. SiC Varactors for Dynamic Load Modulation of Microwave Power Amplifiers

   Author : Christer Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear characterization; varactors; active load-pull; power; microwave; amplifier; dynamic load modulation; SiC; energy efficiency;

   Abstract : The rapid consumer adoption of mobile services is leading to an exponential growth in wireless data traffic. In order to accommodate more concurrent high data-rate users, the required complexity of transmitting radio base station (RBS) power amplifiers (PAs) is increasing. READ MORE
