InP DHBT wideband amplifiers with up to 235 GHz bandwidth

• Two wideband amplifier MMICs are designed and tested. Both designs employ InP double-heterojunction bipolar transistor technology. The amplifiers are designed using cascode cells, in a distributed amplifier topology, with simple on-chip resistive bias circuitry. A single stage design achieves 7.5 dB gain and 192 GHz bandwidth and a 2-cascaded distributed amplifier achieves gain in excess of 16 dB and with bandwidth exceeding 235 GHz, thus being the widest band amplifiers reported to date.
