Abstract:

This article presents a K/Ka-band transmit/receive (T/R) front-end for jointed sensing and communication (JSAC) applications. A reconfigurable matching network for both signal reception and transmission is realized using the proposed triple-coupled transformer (TCT) technique, achieving low power loss and a compact footprint. The T/R switch at …

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 (…
