In this study, a communication system with 10 Gbps data rate is designed and its performance is investigated by using OOK (On-Off Keying) modulation in the 240 GHz band. OOK Modulation is carried out in a relatively low frequency band and is transported to the targeted high frequency band. The frequency downconversion is achieved by multiplying the generated local oscillator signal by the carrier signal from the communication channel. The downconverted signal is demodulated and the recovered signal is observed.
