“…Monolithic integrated power amplifiers (PAs) at this frequency range play a significant role in many applications [1,2]. Among millimeter-wave band, D-band is especially promising for wireless communication due to the ISM band around 122 GHz and the atmospheric window with low freespace attenuation around 140 GHz.…”

In this paper, a D-band power amplifier (PA) based on 0.5-µm InP DHBT is presented. Wilkinson combiners with broadband steppedimpedance matching are used, and the eight-way PA is designed for wideband power performance. As input power is fixed at 3 dBm, the PA exhibits a saturated output power of 16.8 dBm and 7.9% PAE at 150 GHz with >45-GHz 3-dB power bandwidth from 125 GHz to 170 GHz. Meanwhile the 1-dB gain compression output power is 15.9 dBm at 150 GHz. The >45-GHz 3-dB power bandwidth means a great flatness of power gain which is outstanding in reported D-band PAs to our best knowledge.

The paper presents 122 GHz LNAs in SiGe utilizing three transmission line topologies. The amplifiers take advantage of passives like transmission lines and MIM capacitors to realize the input, output and inter-stage matching for the LNAs. Three types of transmission lines are investigated. LNA design methodology and performance comparison of LNAs with the three transmission line topologies are given. The amplifier is intended for the use in ISM band radar systems for consumer application and imaging radar for security and medical diagnostics.Index Terms -LNA, mm-wave circuit design, SiGe, transmission line, 122GHz.
