  1. 1. Direct Conversion Front End for LTE and LTE-A with Frequency-Translational Feedback, Harmonic Rejection Mixer and Input Matching Compensation

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Douglas Andersson Hägglund; [2016]
    Keywords : Technology and Engineering;

    Abstract : This thesis covers the design of a wideband, flexible front end for LTE and LTE-A in a 65 nm CMOS process. A topology with global frequency translational feedback is investigated and a harmonic rejection mixer is implemented. READ MORE

  2. 2. Design of a 30 GHz PLL for use in Phased Arrays

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Byron Murphy; [2016]
    Keywords : pll; phase-locked loop; beamforming; vco; qvco; Technology and Engineering;

    Abstract : This project includes the research and implementation of a high frequency phase-locked loop (30 GHz or more) for beamforming use in a phased antenna array. The phase-locked loop includes a quadrature voltagecontrolled oscillator with a 10% tuning range and 417 degrees of phase control with a 10 degree resolution, a current mode latch in the divide-bytwo configuration operates over the quadrature voltage-controlled oscillator’s tuning range while consuming less than 583 uA of current, Dtype flip flops in a divide-by-8 configuration, a phase-frequency detector, a charge-pump, and a loop filter.

  3. 3. A 1296 MHz Earth-Moon-Earth Communication System

    University essay from Chalmers tekniska högskola/Institutionen för rymd- och geovetenskap

    Author : Magnus Lindgren; [2015]
    Keywords : earth moon communication system;

    Abstract : The task of designing, building and characterizing an Earth–Moon–Earth(EME) communication system in the 1296 MHz amateur radio band hasbeen successfully accomplished. Using the radar equation and thermal noisetheory, in conjunction with measured and estimated system parameters, thelunar echo signal to noise ratio (SNR) has been estimated at 5. READ MORE

  4. 4. Design and Test of an L-Band (GNSS) Low Noise Amplifier and Limiter

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Ms Navneeta; [2015]
    Keywords : Technology and Engineering;

    Abstract : Abstract This thesis work was performed at RUAG Space AB, Göteborg, Sweden. The aim of this thesis is to test the performance boundaries of SiGe based heterojunction bipolar transistor in designing a low noise amplifier meant for GNSS applications. READ MORE

  5. 5. Highly Linear 2.45 GHz Low-Noise Amplifier Design

    University essay from Linköpings universitet/Fysik och elektroteknikLinköpings universitet/Tekniska högskolan

    Author : Atchaiah Bandla; [2015]
    Keywords : Gain; Noise-Figure; Stability.;

    Abstract : One critical component of the communication receiver of front-end system is the low-noise amplifier (LNA). For good sensitivity and dynamic range, the LNA should provide a low noise figure and maximum attainable power gain. Another concern is the linearity of the LNA. READ MORE
