1. 1. Superconducting gates for InP HEMTs

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Sebastian Alveteg; [2023]
   Nyckelord :Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

   Sammanfattning : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. LÄS MER

3. 2. Digital Front End Algorithms for Sub-Band Full Duplex

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Midhat Rizvi; Khaled Al-Khateeb; [2023]
   Nyckelord :Adjacent Channel Leakage Ratio; Bit Error Rate; Clipping and Filtering; Crest Factor Reduction; Digital front end; Digital Pre-Distortion Error Vector Magnitude; Frequency Division Duplex; Power Amplifier; Peak to Average Power Ratio; Peak Cancellation Crest Factor Reduction; Sub Band Full Duplex; Self-Interference Cancellation; Signal-to-Interference Noise Ratio; Signal-to-Noise Ratio; Turbo Clipping; Time Division Duplex; Technology and Engineering;

   Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

4. 3. Investigation of Analog Calibration Systems for Spurious Tone Suppression in Frequency Triplers

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Cristian Alexandru Ghihanis; Barath Copparam Santhanakrishnan Sudarsan; [2023]
   Nyckelord :Delay-Locked Loop; DLL; Edge-Combining; EC; EC DLL; Edge-Combining Delay-Locked Loop; spurious tone calibration; spurs calibration; spurious tones compensation; spurs compensation; Technology and Engineering;

   Sammanfattning : The market for Wi-Fi receiver designs for latest Wi-Fi standards, that cover RF bands in the 2.4 GHz, 5 GHz and 6 GHz spectrum, require increasingly stringent power consumption limitations as more of the market is driven towards battery-powered devices. LÄS MER

5. 4. FEM analysis of existing buildings during renovation

   Master-uppsats, KTH/Hållfasthetslära

   Författare :Agnes Nyberg; [2023]
   Nyckelord :Sturegallerian; Räumlich Finite Element Method; Euro code; Masonry; Steel amplifier; Sturegallerian; Räumlich Finita Element Metod; Eurokoder; Murverk; Stål förstärkning;

   Sammanfattning : In this masters thesis the aim was to investigate a part of Sturegallerian in Stockholm to be reconstructed. The reconstruction did implicate that openings were to be established in an already existing masonry wall. LÄS MER

7. 5. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Berkay Efilti; [2023]
   Nyckelord :Applied Physics; Laser Physics; Fiber Lasers; Fiber Amplifiers;

   Sammanfattning : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.
