  2. 2. High Performance LNAs and Mixers for Direct Conversion Receivers in BiCMOS and CMOS Technologies

    Författare :TOBIAS TIRED; Institutionen för elektro- och informationsteknik; []
    Nyckelord :LNA; mixer; direct conversion receiver;

    Sammanfattning : The trend in cellular chipset design today is to incorporate support for a larger number of frequency bands for each new chipset generation. If the chipset also supports receiver diversity two low noise amplifiers (LNAs) are required for each frequency band. This is however associated with an increase of off-chip components, i.e. LÄS MER

  3. 3. New directions in RF LNA design

    Författare :Stefan Andersson; Christian Fager; Linköpings universitet; []

    Sammanfattning : The RF field develops fast today and to meet the increasing needs from more and more users and higher and higher data rates for mobile terminals the number of wireless standards are rapidly increasing. This has lead to an increased number of frequency spectra dedicated for wireless communication, such as the recent ones for WCDMA, Bluetooth, and WLAN. LÄS MER
