  1. 1. Design and Implementation of a 7-8 GHz Low-Noise Amplifier

    Master-uppsats, Fysik och elektroteknik; Tekniska högskolan

    Författare :Raja Muhammad Awais Khan; Sajid Zaheer; [2012]
    Nyckelord :;

    Sammanfattning : The thesis describes the LNA design for the European UWB regulations for 6.0-8.5 GHz. The design of low-noise amplifier is a critical step while designing the front-end of the receiver architecture. LÄS MER

  3. 2. Co-Design of Antenna and LNA for 1.7 - 2.7 GHz

    Master-uppsats, Fysik och elektroteknik

    Författare :Kane Jacob; Bala Bhaskar Gudey; [2012]
    Nyckelord :ADS; LNA; Antenna; NF; co-design; codesign; E-pHEMT;

    Sammanfattning : In a radio frequency (RF) system, the front-end of a radio receiver consists of an active antenna arrangement with a conducting mode antenna along with an active circuit. This arrangement helps avoid losses and SNR degradation due to the use of a coaxial cable. LÄS MER

  5. 4. Design of GaAs MMIC passive WaveProbes

    Master-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Rameshwor Prasad Shah; [2011]
    Nyckelord :MTEL elektronikk; Radiosystemer;

    Sammanfattning : GaAs MMIC are taking big space in the wireless communication in today’s world. The devices are to be characterized for higher frequencies. External passive waveprobes are used to characterize the devices. As the use and technology is increasing there will be more development on MMICs. LÄS MER

  7. 5. A MMIC GaAs up-converter from 350 MHz to 1835 MHz realized both in a HBT diode-mixer topology and pHEMT resistive FET-mixer topology

    Master-uppsats, Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Författare :Anders Andersson; Joakim Östh; [2006]
    Nyckelord :;

    Sammanfattning : Two mixers for up-conversion from an IF frequency of 350 MHz to a RF frequency of 1835 MHz have been designed and simulated to be used in Ericsson.s radio link system MINI-LINK. One mixer uses diodes in a balanced structure, and the other one use resistive FET-mixers, also in a balanced structure. LÄS MER
