Özet (Çeviri)
Wireless communication technologies have continuously advanced for both performance and frequency aspects, mainly for the frequencies up to 6 GHz. The results of Moore's law now also give the opportunity to design mm-wave circuits using advanced CMOS technologies. The introduction of SiGe into CMOS, providing high performance BiCMOS, has also enhanced both the frequency and the power performance figures. The current situation is that the active devices of both CMOS and BiCMOS technologies can provide performance figures competitive with III-V technologies while having still the advantage of low cost. However, similar competition cannot be pronounced for the passive components considering the low-resistive substrates of BiCMOS technologies. Moreover, both III-V and BiCMOS technologies have the lack of low-loss and low-power consumption, as well as highly linear switching and tuning components at mm-wave frequencies. RF-MEMS switch technologies have been well-known with excellent RF- performance figures. The power consumption of electrostatic RF-MEMS switches is negligible and they can handle higher power levels compared to their semiconductor counterparts. However, RF-MEMS switches have been mostly demonstrated as standalone processes and have started to be used as commercial off-the-shelf (COTS) devices recently. The full system integration is typically done by a System-in-Package (SiP) approach. Although SiP is suitable for lower frequencies, the packaging parasitics limit the use of this approach for the mm-wave frequencies. In this thesis, a fully BiCMOS embedded RF-MEMS switch for mm-wave applications is proposed. The design, the implementation and the experimental results of the switch are provided. The developed RF-MEMS switch is packaged using different packaging approaches. To actuate the RF-MEMS switch, an on-chip high voltage generation circuit is designed and characterized. The robustness and the reliability performance of the switch are also presented. Finally, the developed RF-MEMS switch is successfully demonstrated in re-configurable mm-wave circuits.
