Optoelectronic switching for antenna networks

Optoelectronic switching for antenna networks

An optoelectronic switch with a 4.5 GHz bandwidth has been fabricated and tested in a simulated antenna network environment. The experiment demonstrated the detection of L-band FM video channels and S-band microwave BPSK channels. The measured electrical crosstalk isolation was better than 29 dB.<...
