## Abstract High‐gain shunt‐series shunt‐shunt wideband amplifiers with and without emitter‐peaking capacitors are demonstrated by using GaInP/GaAs HBT technology. Experimental results show that the power gain is 28 dB from DC to 6 GHz for a wideband amplifier without emitter‐peaking capacitors. On
