Abstract :
A monolithic 10 channel limiting amplifier for high speed optical fibre communication systems based on 0.3 μm gate length enhancement and depletion AlGaAs/GaAs HEMTs (fT=50/45 GHz) has been fabricated. Each channel has a small signal differential gain of 35 dB and a bandwidth of 8.5 GHz; the amplifier array operates reliably up to 10 Gbit/s. The differential output voltages are limited to 1.2 VP-P . The power consumption is 2.5 W at a single supply voltage of -5 V
