-
This thesis presents radio frequency integrated circuits and subsystems,
together with packaging solutions, for fully integrated compact and low cost
Silicon-Germanium (SiGe) 24 GHz transceivers developed during the European
Commission funded project ARTEMIS.
The circuits have been manufactured using a commercially available SiGe
HBT semiconductor process at ATMEL (Heilbronn, Germany) featuring
transistors with 0.8 ìm emitter structures, fmax=90 GHz and fT=80 GHz.
For all circuits, standard 20 Ohmcm substrate has been used.
Sub-circuits that have been designed and manufactured are 12 GHz VCO:s,
polyphase filters, LO pump amplifiers, LNA:s, down- and up-conversion
subharmonic mixers, complete receivers and complete transmitters. Measured
results of individual circuit blocks, subsystems (e.g. VCO together with
polyphase filter) and system performances is presented.
A low loss 24 GHz chip-to-PCB transition using Low Temperature Co-fired
Ceramic (LTCC) packaging has been manufactured and evaluated, including
a balun structure to interface the differential RFIC with a high gain single
ended off-chip patch antenna array.
Finally, measurement techniques for on-chip differential circuits is
presented.
