DIFFERENTIAL DUPLEXER SYSTEMS WITH PHASE SHIFTERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240088921 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 provide differential received signals to the receiver and receive differential transmission signals from the transmitter for transmission. This setup allows for improved isolation and reduced signal interference.
- The duplexer is equipped with phase shifters on the differential lines to convert single-ended received signals to differential received signals and vice versa for transmission.
- The phase shifters also provide single-ended transmission signals to antennas for transmission and to the differential lines of the receiver for cancellation/isolation.
- Differential received signals are provided to the receiver for reception, while single-ended received signals are sent to the differential lines of the transmitter for cancellation/isolation.
Potential Applications
The technology described in the patent application could be applied in various communication devices such as smartphones, radios, and other wireless devices.
Problems Solved
This technology helps in reducing signal interference and improving isolation in communication devices, leading to better signal quality and reliability.
Benefits
The use of differential coupling and phase shifters in the duplexer enhances the performance of communication devices by providing improved isolation and reducing signal interference.
Potential Commercial Applications
The technology could be utilized in the development of advanced communication devices for commercial use, such as in telecommunications, IoT devices, and wireless networks.
Possible Prior Art
One possible prior art could be the use of traditional duplexers in communication devices, which may not provide the same level of isolation and signal interference reduction as the technology described in the patent application.

The article does not address the potential challenges in implementing this technology in mass-produced communication devices. Factors such as manufacturing complexity, compatibility with existing systems, and cost implications would need to be considered in the implementation process.
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.
