摘要：
Resonant tunnelling diode (RTD) oscillators used for high-speed terahertz wireless communication systems have garnered significant attention in recent years. In these systems, RTD devices are directly on-off modulated through baseband (BB) circuits, which limit the data rate. This letter investigates an efficient approach to increase the bandwidth of the BB circuits, by addressing the broadband connection between the two-RTD oscillator chip and the radiofrequency circuit board. As a result, an error-free wireless communication has been achieved with a data rate of 25 Gbit/s in the 300-GHz band using the RTD transmitter and receiver.
