Abstract
This paper reports on the design, fabrication, and
characterization of a lumped broadband amplifier in SiGe bipolar
technology. The measured differential gain is 20 dB with a 3-dB
bandwidth of more than 84 GHz, which is the highest bandwidth
reported so far for broadband SiGe bipolar amplifiers. The re-
sulting gain bandwidth product (GBW) is more than 840 GHz.
The amplifier consumes a power of 990 mW at a supply of
5.5 V.
