Abstract
A direct-coupled. lumped broadband amplifier utilising InP/InGaAs single he terojunction bipolar transistors (SHBTs) is presented. The achieved -3dB ba ndwidth is 50GHz with a DC gain of 9.8dB and a gain peak of only 1.2dB. Thi s is thr largest bandwidth repot-ted For InP/InGaAs HBT amplifiers with suc h a flat gain curve.
