Ultrawideband 131–173-GHz dual receiver implemented in GlobalFoundaries 45RFSOI technology

131-173 GHz (D-band)

The system frequency plan minimizes RF leakage into the local oscillator (LO) and RF bands of operation. Superior image rejection is a natural result of the hi-IF frequency plan due in part to the inherent frequency response of the low noise amplifier (LNA). On-chip x6 LO path and triple wideband LNA architecture achieves state-of-the-art ultrawide 42 GHz bandwidth (BW) and 5.7 dB noise figure performance for the highest know figure of merit (FoM) for a CMOS D-band receiver.

Point-to-point sub-THz 6G communications

24.4 dB minimum gain (131-173 GHz); 42 GHz 3db BW; 5.7-8.4 dB NF; -32.5 to -28dBm IP1dB; -21 to -20 dBm IIP3; 2x40 Gb/s data rate using 32 QAM with 9.8% to 13.5% EVM. 297 mW DC power consumption (179 mW for the LO path); 0.77 mm2 chip area.
