Abstract:

This article presents a 28-nm CMOS sub-terahertz (sub-THz) amplitude shift-keying (ASK) transceiver achieving competitive wireless and wireline communication performance. The over-the-air (OTA) link demonstrates 14 Gb/s/0.27 km, 16Gb/s/1m, and 27 Gb/s/12 cm without equalization (EQ), while supporting 64 Gb/s on-Off keying (OOK) and 40 Gb/s pulse amplitude modulation (…

A High-Power Wideband Sub-THz Power Amplifier With Asymmetric Slotline-Based Series–Parallel Combiner in 130-nm SiGe BiCMOS Technology

A High-Power Wideband Sub-THz Power Amplifier With Asymmetric Slotline-Based Series–Parallel Combiner in 130-nm SiGe BiCMOS Technology 150 150
Author(s): Gunwoo Park, Hyunjoon Kim, Sanggeun Jeon

Abstract:

This article presents a high-power, wideband sub-terahertz power amplifier (PA) implemented in a 130-nm SiGe BiCMOS technology. The PA features a novel asymmetric slotline-based series–parallel combiner (ASSPC) for output power combining. The ASSPC provides both low-loss, wideband combining and efficient admittance matching for four differential cascode PA unit cells, …
