90, 180 and 360 GHz Fully Integrated Differential Signal Source With Hyper-Wideband Continuous Tuning Range (TR) in 90 nm SiGe:C BiCMOS Technology B12HFC from Infineon AG

90 GHz, 180 GHz, 360 GHz

All circuit fabrication done with preproduction 90 nm SiGe:C BiCMOS technology B12HFC from Infineon Technologies AG. Dividing down the 90 GHz VCO significantly reduces cost and complexity for frequency stabilization and chirp generation.
