A 50-Gbit/s demultiplexer IC module that uses 0.1-µm InAlAs/InGaAs/InP HEMTs is reported. The maximum error-free operation bit-rate of a fabricated module is 50 Gbit/s, and a wide phase margin of 170 degrees is obtained at 43 Gbit/s. 50-Gbit/s demultiplexing is the fastest performance of all packaged demultiplexer ICs yet reported.
