A fundamental OOK modulator for 340 GHz communication using 0.13 μm CMOS technology

This letter presents a 340 GHz fundamental on–off keying modulator using 0.13 μm CMOS technology. The proposed modulator topology is composed of a 90° hybrid coupler and two series loads formed by a series inductor and a MOSFET for 340 GHz on-/off-state switching. The measured results indicate that the insertion loss is ∼4.9 dB on average and the isolation is better than 13 dB from 330 to 347 GHz. A measured data rate of 2.5 Gb/s is demonstrated at the carrier frequency of 340 GHz. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1166–1168, 2015
