==DIFFERENTIAL DOUBLE BALANCED DUPLEXER - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17945826 titled 'DIFFERENTIAL DOUBLE BALANCED DUPLEXER

==Simplified Explanation==

The differential double balanced duplexer (dDBD) described in the patent application is a device that allows for increased isolation and decreased insertion loss in communication systems. Here are some key points to explain this innovation:

* The dDBD includes a transmitter, a receiver, and two baluns that are each coupled to an impedance tuner.
* The first impedance tuner connected to the transmitter produces an impedance that blocks received signals at a certain frequency range from entering the transmitter, while allowing transmitted signals at a different frequency range to pass through to the antenna.
* The second impedance tuner connected to the receiver allows received signals at the same frequency range to enter the receiver, while blocking transmitted signals at the different frequency range from reaching the receiver.

Potential Applications:
The dDBD technology can be applied in various communication systems such as cellular networks, radar systems, and satellite communication to improve signal isolation and reduce insertion loss.

Problems Solved:
The dDBD solves the problem of signal interference between the transmitter and receiver in communication systems, leading to improved overall performance and signal quality.

Benefits:
The main benefits of the dDBD technology include increased isolation between the transmitter and receiver, decreased insertion loss, and improved signal integrity in communication systems.

Potential Commercial Applications:
The dDBD technology can be commercially applied in the telecommunications industry, defense sector, and aerospace industry for enhancing the performance of communication systems.

Possible Prior Art:
One possible prior art for this technology could be traditional duplexers or baluns used in communication systems to separate and combine signals, but they may not provide the same level of isolation and insertion loss reduction as the dDBD.

Unanswered Questions:
1. How does the dDBD technology compare to other existing duplexers in terms of performance and cost-effectiveness?
2. Are there any specific frequency ranges or communication standards where the dDBD technology is most effective compared to other solutions?


==Original Abstract Submitted==

A differential double balanced duplexer (dDBD) includes a transmitter and a first balun are coupled to a first impedance tuner that produces a first impedance that blocks received signals at a first frequency range from travelling across the first balun and into the transmitter, and a second impedance that passes transmitted signals at a second frequency range to travel across the first balun to the antenna. The dDBD also includes a receiver and a second balun coupled to a second impedance tuner that produces a first impedance that allows the received signals at the first frequency range to travel across the second balun and into the receiver, and a second impedance that blocks the transmitted signals at the second frequency range from travelling across the second balun and into the receiver. As such, the dDBD allows for increased isolation and decreased insertion loss.
