First results show a data rate of over 20 Gbit/s at 5 V supply voltage and 250 mW power consumption. The output voltage swing is adjustable between 0.3 V and 0.8 V for a 50 Ohm load. The output level can be varied between plus1 V an minus1 V. Comparison between simulation and measurement shows very good agreement.encommunication systemE/D Transistorhigh-speed switchHochgeschwindigkeitsschalterKommunikationssystemmultiplexersource coupled fet logictest equipment instrumentationTestgerät62166720 Gbit/s 2 to 1 multiplexer using 0.3 mym gate length double pulse doped Quantum Well GaAs/AlGaAs transistors.20 Gbit/s 2 zu 1 Multiplexer unter Verwendung von Doppel Puls dotiertem Quantum Well GaAs/AlGaAs Transistoren mit einer Gate-Länge von 0.3 mymjournal article
