Spectrum Analyzer Extenders at 300 GHz Enabling Complex 16-QAM Modulation

The development of wireless communication systems operating at millimeter wave frequencies has become crucial to meet the rapidly increasing demand for high data rates and low-latency communications. Terahertz (THz) communication links offer unprecedented bandwidth, enabling data rates of several tens to hundreds of gigabits per second (Gbps). This paper demonstrates the transmission and reception of a 16-QAM modulated signal at 300 GHz using spectrum analyzer extenders fully designed, developed and manufactured at ACST GmbH [1]. The spectrum analyzers used in this study were provided by Aaronia AG [2].
