A high-speed selector module has been developed. It is constructed from a selector IC mounted in a ceramic package, a power supply unit, phase shifters, and coaxial cables. The IC was designed using LSCFL and fabricated with 0.2 mu m gate length GaAs MESFETs. The selector module operated above 25 Gbit/s. It is expected to be applied to high-speed IC measurements.<<ETX>>
A 2 bit multiplexer (MUX) and demultiplexer (DEMUX) with D-type flip-flops (DFFs) for input and output retiming were developed. The ICs were designed using two-level series-gated ECL and realised by AlGaAs/GaAs ballistic collection transistors with launcher (L-BCT) technology. The maximum operating speeds if the ICs were 19 Gbit/s for the MUX and 17 Gbit/s for the DEMUX. These error free operating...
