Fig. 7: Trends seen in sub-THz transmitter output power and data rates as well as trends seen in sub-THz receiver gain and noise figure.
From: Sub-THz communication systems: pushing the capabilities of silicon

The values from Tables 1 & 2 arranged to show interesting trends in recent years. (top-left) Transmitter output power decreases with frequency. (top-right) Data rate slightly decreases with frequency. (bottom-left) Receiver noise figure increases with frequency. (bottom-right) Receiver gain decreases with frequency.
