A +70-dBm IIP3 Electrical-Balance Duplexer for Highly Integrated Tunable Front-Ends
Barend van Liempd,Benjamin Hershberg,Saneaki Ariumi,Kuba Raczkowski,Karl-Frederik Bink,Udo Karthaus,Ewout Martens,Piet Wambacq,Jan Craninckx +8 more
TL;DR: In this paper, an electrical-balance duplexer achieving the state-of-the-art linearity and insertion loss (IL) performance is presented, enabled by a partially depleted RF silicon-on-insulator CMOS technology.
Journal ArticleDOI
A SAW-Less Tunable RF Front End for FDD and IBFD Combining an Electrical-Balance Duplexer and a Switched- LC N-Path LNA
TL;DR: This paper proposes a surface-acoustic wave (SAW)-less tunable RF front end (RF-FE) using an electrical-balance duplexer (EBD) integrated with a switched-LC N-path low-noise amplifier (LNA) that cancels the transmitter–receiver (TX–RX) leakage at the RX frequency by dynamically optimizing the balance of a hybrid transformer.
