  1. 1. 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. 2. Integrated Transceivers for Millimeter Wave and Cellular Communication

    Nyckelord :receiver; LNA; mixer; bipolar; BiCMOS; SiGe; mm-wave; E-band; transmitter; PLL; PA; beam steering;

    Sammanfattning : Abstract:This doctoral thesis is addresses two topics in integrated circuit design: multiband direct conversion cellular receivers for cellular frequencies and beam steering transmitters for millimeter wave communication for the cellular backhaul. The trend towards cellular terminals supporting ever more different frequency bands has resulted in complex radio frontends with a large number of RF inputs. LÄS MER
