  1. 1. 1kW Class-E solid state power amplifier for cyclotron RF-source

    University essay from Uppsala universitet/FREIA

    Author : Stefan Book; [2018]
    Keywords : Class-E; LDMOS; high efficiency; high power; VHF; power amplifier; accelerator; cyclotron;

    Abstract : This thesis discusses the design, construction and testing of a highefficiency, 100 MHz, 1 kW, Class-E solid state power amplifier. The design was performed with the aid of computer simulations using electronic design software (ADS). The amplifier was constructed around Ampleon's BLF188XR LDMOS transistor in a single ended design. READ MORE

  2. 2. A High Efficiency and Wideband Doherty Power Amplifier for 5G

    University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

    Author : Halil Volkan Hünerli; [2017]
    Keywords : ;

    Abstract : In today’s wireless communications, mobile networks need high data rates and low power consumption. For this purpose, novel wideband and energy efficient power amplifiers should be designed. This thesis is concerned with this problem. READ MORE

  3. 3. Electrical Pulsing of a Laser Diode for Usage in Fluorescence Microscopy

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Karin Jerner; [2017]
    Keywords : electrical pulsing; laser pulsing; fluorescence microscope; laser diode;

    Abstract : A relatively new application for the laser is in fluorescence microscopes. The fluo- rescence microscope needs a high power light source input. Using a laser source improves the precision of the microscope. A pulsed laser source enhances the performance of the fluorescence microscope and a laser diode can be overdriven without being damaged.

  4. 4. Development of a Class D motor amplifier for a next-generation mechanism control electronics

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Juan Camilo Garcia Hernandez; [2016]
    Keywords : Power; electronics; satellites; BLDC; sinusoidal; commutation; control; PID; class D amplifier; PWM;

    Abstract : This thesis was written at Airbus DS GmbH in Friedrichshafen, Germany, as part of a project which aims to develop a new generation of class-D power amplification circuits for sinusoidal commutating motors controlling the movement of different mechanisms in satellites. Currently used topologies have disadvantages such as high power loss, analog controlling and high degree of signal distortion. READ MORE

  5. 5. Integrated CMOS Doppler Radar : Power Amplifier Mixer

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Olof Sjöholm; [2016]
    Keywords : Doppler Radar Power Amplifier Mixer CMOS RF;

    Abstract : This thesis is based on a paper by V. Issakov, presented 2009, where a circuit of a merged power amplifier mixer solution was demonstrated. This work takes that solution and simplifies it for the use at a lower frequency. The implementation target is a Doppler radar application in CMOS that can detect humans in a range of 5 to 15 meters.
