Frequency-Translational Quadrature-Hybrid Receivers for Frequency-Agile Massive Carrier Aggregations [D28]

To accommodate the predicted 1000x data throughput growth in 5G communications, massive carrier aggregation (CA) is becoming one of the key technologies to boost system bandwidth.  Different regional spectrum policies lead to a large number of band combinations and challenge the conventional receiver architecture. Filter bank designs become extremely complex and costly. Thus, we demonstrate a new RF receiver architecture named frequency-translational quadrature-hybrid (FTQH) receivers for massive carrier aggregation. The FTQH receivers breaks the constraint between antenna impedance matching and the LNA input impedance by marrying design techniques of microwave circuits and CMOS analog IC. This facilitates the use of highly reflective LNAs and voltage domain wideband RF signal splitting. In this demo setup, three FTQH receivers are connected as an RF daisy chain to support as much as six-band downlink carrier aggregation. Six modulated signals are generated, received and analyzed in real time to demonstrate frequency-agile massive carrier aggregations.
