Abstract :
Key components of sensor front-ends have been realized for the frequency range beyond 100 GHz in a SiGe bipolar technology. The circuits presented include 110 GHz push-push and fundamental VCOs, both with up to 0 dBm ouput power, as well as fixed-frequency oscillators at 121 and 124 GHz. Furthermore, 122 GHz down-conversion mixers are demonstrated.
