Abstract

Using our 0.2 μm AlGaAs/GaAs quantum well high electron mobility transistor (HEMT) technology, we have developed time division multiplexer chips. A 2:1 multiplexer for data rates up to 50 Gbit/s and a 4:1 multiplexer designed for easy implementation into existing fiber-optical digital transmission systems to speed up their data rates to 40 Gbit/s. Both circuits can be operated on a single power supply in the range of -3 V to -5.5 V. The power dissipation is 2.8 W and 1.7 W respectively at 4.0 V supply voltage
