Flip-chip mounted 1:4 demultiplexer IC in InP DHBT technology operating up to 100 Gb/s

Operation of a packaged 1:4 demultiplexer (DEMUX) in InP DHBT technology for an input data rate of up to 100 Gb/s is presented. The DEMUX IC is flip-chip mounted in a microwave package consisting of an aluminum nitride substrate with coplanar waveguides placed in a Kovar/MoCu housing with coaxial V-connectors. The DEMUX was operated at a supply voltage of -3.5 V and consumes 2.1 W.
