DIFFERENTIAL DUPLEXER SYSTEMS WITH PHASE SHIFTERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17945023 titled 'DIFFERENTIAL DUPLEXER SYSTEMS WITH PHASE SHIFTERS
Simplified Explanation
The communication device described in the patent application includes a duplexer that is differentially coupled to a receiver and a transmitter. The duplexer utilizes phase shifters on the differential lines to handle differential received signals to the receiver and receive differential transmission signals from the transmitter for transmission. The phase shifters are strategically positioned to convert single-ended received signals to differential received signals and convert the differential transmission signals to single-ended transmission signals for transmission. Additionally, the phase shifters play a role in providing single-ended transmission signals to antennas for transmission and to the receiver's differential lines for cancellation/isolation. They also provide the differential received signals to the receiver for reception and the single-ended received signals to the transmitter's differential lines for cancellation/isolation. Overall, the duplexer facilitates communication signal conveyance while reducing signal interference through improved isolation.
- Duplexer is differentially coupled to receiver and transmitter
- Phase shifters on the differential lines convert single-ended signals to differential and vice versa
- Phase shifters provide signals for transmission and reception, as well as for cancellation/isolation

Original Abstract Submitted
A communication device includes a duplexer differentially coupled to a receiver and a transmitter. The duplexer may include phase shifters on the differential lines to provide differential received signals to the receiver and receive differential transmission signals from the transmitter for transmission. For example, the phase shifter are positioned such that single-ended received signals may be converted to differential received signals and convert the differential transmission signals to single-ended transmission signals for transmission. Moreover, the phase shifters may provide the single-ended transmission signals to antennas for transmission and to the differential lines of the receiver for cancellation/isolation. Furthermore, the phase shifters may provide the differential received signals to the receiver for reception and provide the single-ended received signals to the differential lines of the transmitter for cancellation/isolation. Accordingly, the duplexer may convey communication signal while reducing signal interference by providing improved isolation.
