Abstract
Single-stage and two-stage differential cascode amplifiers, and a 2:1 multiplexer, fabricated in InP/InGaAs HBT technology and powered from less than 5 V supplies, are presented. The amplifiers have typical DC gains of 21 and 33 dB, respectively, and unity-gain bandwidths in excess of 15 GHz, with approximately 20 dB gain at 10 GHz. The multiplexer was tested at rates up to 20 Gbit/s.
