Recently, we demonstrated a D-band (110–170 GHz) distributed amplifier by embedding transistors in the middle of an SIW as voltage probes. The voltage probes are realized through hot through-substrate ...

For North American TDMA and CDMA phones, dual-band indicates that the phone will work in both the 800/850 MHz band and the 1900 MHz band. Most current TDMA phones in the U.S. are tri-mode ...

Abstract: A record continuous transmission bandwidth of 16.4 THz is demonstrated in O-band fibre transmission over an 80-km single-mode ultra low-loss fibre span. Bismuth-doped fibre amplifiers with ...
