Optimising the performance of an optically controlled microwave switch

Optically controlled reconfigurable antenna for 5G future broadband cellular communication networks

“…In this way, its conductivity becomes reconfigurable as a function of the incident optical power. As soon as the photoconductive switch is illuminated, silicon semi-conductor changes for a conducting state by creating electron-hole pairs [19]. The incident photons must have enough energy to move electrons from the valence to the conduction band.…”

Intermodulation distortion in a photoconductive microwave switch

“…The transmission line topology has been optimized in a previous study [13]. The switch is designed on 0.52 mm thick Rogers 3003 substrate which is mounted on an aluminum ground plane.…”

Reconfigurable Radio-Over-Fiber Networks [Invited]

“…6 [30,31], including the photonic downconversion stage. The RF signal is generated using a vector signal generator (VSG) with an internal digital-to-analog converter (DAC).…”
