Summary
To meet the ever increasing demanding for higher data rate communication, the frequency bands above 100GHz is utilized. The possible frequency band is the D-band (110-170 GHz), where a slot between 141.5 to 148 GHz is possible because of favorable characteristics close to the E-band. Unfortunately, the building blocks for “THz system” transceivers are either too expansive or too bulky. The power efficiency is also not good enough. Developing wireless transceivers (>100GHz) to overcome existing disadvantages is a challenge. The proposed project is aiming at development of D-band highly integrated receiver and transmitter chip sets for spectrum and power efficient wireless transceiver utilizing a high speed InP DHBT process, which is also a part of research activity for the SSF funding project: “RFIC solutions for very high data rage, energy and spectrum efficient wireless THz communication”. Together with researchers in Chalmers University, Mingquan Bao has worked on 140 GHz fully integrated transceiver in 250 nm InP DHBT process since 2012, and achieved a world record highest datarate of 44 Gb/s in D-band. The next step is improving the performance of the D-band transceiver, targeting high order modulation signals, thus, achieve a better spectral efficiency. Consequently, the linearity and noise performance of different building blocks in the transceiver need to be improved.
Popular science description
To meet the ever increasing demanding for high speed communication, the frequency bands above 100GHz is utilized. Unfortunately, the transceivers for the frequency above 100GHz are either too expansive or too bulky. The power efficiency is also not good enough. Developing wireless transceivers (>100GHz) to overcome existing disadvantages is a challenge. The proposed project is aiming at development of highly integrated circuits to reduce the transceiver’s size and the DC power consumption by utilizing an advanced semiconductor technology. This research activity is also a part of the SSF funding project: “RFIC solutions for very high data rage, energy and spectrum efficient wireless THz communication”. Together with researchers in Chalmers University, Mingquan Bao has worked on 140 GHz fully integrated transceiver since 2012, and achieved a world record highest datarate of 44 Gb/s in D-band. The next step is improving the performance of the 145GHz transceiver, enabling the transceiver to be used in larger than 1 km distance point-to-point wireless link.
