| Sumario: | This work describes the design and validation of small-form-factor bidirec- tional radio head units with antennas, photonic devices and RF circuitry for 5G FR1 (sub-7 GHz) wireless radio-over-fibre (RoF) use. The solu- tion offered focuses on low-cost, scalable architecture by repurposing com- mercial off-the-shelf (COTS) optical sub-assemblies in TO-CAN packages, originally designed for application in small form-factor pluggable (SFP) modules up to 10 Gbps. To interface the optical components, the impedance characteristics of the photonic devices were characterized by on-wafer coplanar probe measure- ments. These measurement parameters guided the design of a circuit built in a Rogers-3003 that offers low-loss behaviour over the frequency band of interest. Electromagnetic simulations were performed to validate impedance match- ing and performance, determining the viability of the proposed design for RoF-based 5G. Such integration offers both compactness and cost- effectiveness, moving towards deployable, integrated and fibre connected radio heads in future wireless networks. |
