InP DHBT-based ICs for 100 Gbit/s data transmission


This paper reports state-of-the-art mixed signal ICs, including a distributed amplifier and a multiplexer-core intended for use in 100 Gbit/s optical communication systems (Ethernet). Using a manufacturable InP DHBT technology, exhibiting current gains of >80 and cut-off frequencies (fT and fmax) of >300 GHz, the broadband amplifier achieved a gain of 21 dB… (More)
