W-band Distributed Antenna System Using Low-Pass Sigma-Delta-over-Fiber

Paper in proceeding, 2024

This paper explores the high-frequency communication bands for greater data rates. Specifically, the study introduces a W-band distributed radio-over-fiber system operating at a carrier frequency of 100 GHz. The system employs a low-pass signal-delta-over-fiber architecture, utilizing commercially available off-the-shelf hardware components. Experimental findings reveal a competitive system performance, achieving a symbol rate of 1.5 Gsym/s over a 2 m over-the-air transmission distance. Significantly, this work marks the pioneering demonstration of a distributed antenna system for W-band applications.
