A low cost 10 Gbit/s millimeter wave wireless link working at E band

Test results for a 10-Gbps prototype demonstrator working at 71~76 GHz frequency band with a 2-bit/s/Hz spectral efficiency are reported. To overcome the speed limitation of the commercial DA/ADs, a two-channel analog IF multiplexing and demultiplexing topology is adopted as a trade-off between cost
