Today, measurement of 65 nm CMOS and 130 nm-based SiGe HBTs technologies demonstrate both Ftau (current gain cut-off frequency) and Fmax (maximum oscillation frequency) higher than 200 GHz, which are clearly comparable to advanced commercially available 100 nm III-V HEMT. Consequently, the integration of full transceiver at 60 GHz has been achieved both in SiGe bipolar and CMOS technology. In the...
