  1. 1. Compact Ku-band Microwave Filters Realised using Suspended Integrated Stripline Technology

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Henrik Åkerberg; [2023]
    Keywords : Suspended Substrate Stripline; Microwave filter; Low Profile; Quasi-Planar; Bandpass Filter; Hängande-Substrat-Stripline; Mikrovågsfilter; Låg profil; Kvasi-planar; Bandpassfilter;

    Abstract : As the fifth generation of telecommunications is deployed, and the number of devices transmitting in the microwave bands grows, effective filtering technologies are becoming ever more important. When a filter is designed, some performance trade-offs have to be made, and one of them is the trade-off between filter size and electrical performance. READ MORE

  3. 2. Model Based Reinforcement Learning for Automatic Tuning of Cavity Filters

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Doumitrou Daniil Nimara; [2021]
    Keywords : Reinforcement Learning; Cavity Filter Tuning; Sample Complexity; Background Planning; Förstärkande inlärning; inställning av kavitetsfilter; provkomplexitet; bakgrundsplanering;

    Abstract : As telecommunication continues developing, the demand for mass production of well calibrated Base Transceiver Stations (BTS) components increases. Cavity Filters are an essential piece of every BTS; however, manufacturing tolerances often lead to detuned filters which require costly post-production fine tuning. READ MORE

  4. 3. Reinforcement Learning with Imitation for Cavity Filter Tuning : Solving problems by throwing DIRT at them

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Lindståhl; [2019]
    Keywords : ;

    Abstract : Cavity filters are vital components of radio base stations and networks.After production, they need tuning, which has proven to be a difficultprocess to do manually and even more so to automate. READ MORE

  5. 4. Deep Reinforcement Learning for Cavity Filter Tuning

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Hannes Larsson; [2018]
    Keywords : Reinforcement Learning; Cavity Filter; Deep Learning; Machine Learning; Automation;

    Abstract : In this Master's thesis the option of using deep reinforcement learning for cavity filter tuning has been explored. Several reinforcement learning algorithms have been explained and discussed, and then the deep deterministic policy gradient algorithm has been used to solve a simulated filter tuning problem.

  6. 5. Near-infrared optical frequency comb Vernier spectroscopy in air and in a flame

    University essay from Umeå universitet/Institutionen för fysik

    Author : Maryam Fakhri; [2017]
    Keywords : ;

    Abstract : A Vernier spectrometer is built with a near-infrared mode-locked Er:doped fiber laser, a Fabry-Perot cavity with finesse of 1000, a diffraction grating and a photo detector. The optical cavity provides high sensitivity in absorption detection by enhancing the interaction length of the light with molecular species contained in the cavity. READ MORE
