    Sammanfattning : Short high-frequency electromagnetic pulses, also referred to as wavelets, are considered for use in various short-range impulse based ultra-wideband applications, such as communication, imaging, radar, spectroscopy, and localization. This thesis investigates field-effect and tunneling based semiconductor devices and their operation in millimeter-wave (mm-wave) impulse transceivers. LÄS MER

  5. 4. Heterostructure Diodes for Millimeter Wave Power Generation

    Författare :Hans Grönqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single barrier varactor diode; AlSb barrier; InAs substrate; high frequencies; Resonant Tunneling Diode;

    Sammanfattning : This thesis deals with two types of heterostructure diodes namely the Resonant Tunneling Diode (RTD) and the Single barrier varactor diode (SBV). The RTD is a device for high frequency generation either as a negative reistance oscillators or as a multiplier. Different means to reach high frequencies are outlined. LÄS MER

  7. 5. Millimeter-Wave Impulse Radio

    Författare :Mats Ärlelid; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compound semiconductor; resonant tunneling diode; ultra wideband; 60 GHz; on-off keying; transmitter; receiver; and super-regenerative oscillator;

    Sammanfattning : This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. LÄS MER
