Division Free Duplex in Small Form Factors

Full duplex transceiver technology will only be deployed in future mobile devices if the self-interference cancellation hardware can meet the demanding low-cost and small form factor requirements of handset applications. Electrical Balance Duplexing enables simultaneous transmission and reception from a single antenna, making it an attractive choice for duplexing in mobile devices. In this talk we present our prototype full-duplex transceiver which combines Electrical Balance Isolation with active analogue cancellation to provide high transmit-to-receive isolation over wide bandwidths using low cost small form factor technologies.
