A 410 GHz OOK Transmitter in 28 nm CMOS for Short Distance Chip-to-Chip Communications

This paper presents a 410 GHz OOK transmitter in 28 nm bulk CMOS. The transmitter is packaged together with a metal coated 3D printed horn antenna and has a measured EIRP of -3.99dBm. Modulated measurements are demonstrated through a dielectric waveguide channel. 5 Gbps is demonstrated over a 13 cm channel and up to 1 Gbps over a 61 cm long channel. The transmitter provides a solution for high frequency short distance chip-to-chip or intra-board interconnects.
