A D-band Foam-Cladded Dielectric Waveguide Communication Link with Automatic Tuning

© 2018 IEEE. This paper presents a 140 GHz fully packaged frequency shift keying transceiver with automatic tuning loop for dielectric waveguide communication. A novel receiver topology is proposed to enable mitigation against process, voltage and temperature variations using an automatic tunable phase shift in the LO distribution. Implemented in 28 nm CMOS, the design has a total power consumption of 230 mW and occupies an active area of 0.9 mm2. The measured link achieves a data rate of 10 Gbps/7 Gbps over a 2 m/4 m foam-cladded and thus touchable PTFE channel.status: publishe
