DUPLEXER ARCHITECTURE USING 90 DEGREE HYBRID COUPLER BASED BALANCING CONDITIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240088538 titled 'DUPLEXER ARCHITECTURE USING 90 DEGREE HYBRID COUPLER BASED BALANCING CONDITIONS

Simplified Explanation

The abstract describes an electronic device with isolation circuitry that includes a 90-degree hybrid coupler to split and phase-shift signals between a transmitter, receiver, and antennas.

• The isolation circuitry receives a transmission signal from the transmitter and splits it into two portions, shifting their phase by 90 degrees to be out-of-phase.
• Phase shifters then adjust the phase of the portions to be in-phase before they reach the antenna.
• The phase shifters also handle receiver signals, adjusting their phase by -90 degrees before combining them with the transmitter signals.
• The 90-degree hybrid coupler further adjusts the phase of the signals to be in-phase and combine effectively before reaching the receiver.

Unanswered Questions

How does this technology impact the size and weight of the electronic device?

The abstract does not provide information on the size and weight implications of implementing this technology. It would be important to understand if the addition of isolation circuitry affects the overall form factor of the device.

What are the potential cost implications of integrating this technology into electronic devices?

The abstract does not address the cost considerations associated with implementing this technology. It would be valuable to know if the addition of isolation circuitry increases the manufacturing cost of the device.

Original Abstract Submitted

an electronic device may include isolation circuitry coupled between a transmitter, a receiver, and one or more antennas. the isolation circuitry may include a 90 degree hybrid coupler configured receive a transmission (tx) signal from the transmitter, split the tx signal into a first portion and a second portion, and phase-shift a portion such that the portions are +90 degrees out-of-phase. the isolation circuitry may include phase shifters that phase-shift the portions such that the portions are in-phase prior to propagating to the antenna. the phase shifters may receive a first portion and a second portion of a receiver (rx) signal from splitter circuitry. the phase shifters may phase-shift the portions such that the portions are out-of-phase by −90 degrees. the 90 degree hybrid coupler may phase-shift the first portion and/or the second portion such that the portions are in-phase and constructively combine prior to propagating to the receiver.
