Integrated Wideband Transceiver Feedback Loop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wideband transceivers require a separate feedback receiver within the transmitter, increasing board area, cost, and power consumption, as well as complicating linearity adjustments.
Innovation Solution
An integrated wideband transceiver system where the transmitter and receiver are coupled to form a closed loop, allowing the transmitter to pass signals through the receiver, eliminating the need for a separate feedback receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate feedback receiver is used within the transmitter, then the transmitter operation can be adjusted, but the board area, cost, and power consumption increase
Solution Approach 1:
The patent merges the feedback receiver functionality with the main receiver by coupling the transmitter and receiver to form a closed loop. The transmitter passes signals through the receiver, allowing the receiver to perform both its primary function and the feedback function, thereby eliminating the need for a separate feedback receiver and reducing board area
Solution Approach 2:
The receiver is designed to serve multiple functions: it acts as both the primary signal receiver and the feedback receiver for the transmitter. By making the receiver universal, the patent eliminates the need for dedicated feedback receiver components, reducing overall system complexity and board area
2Reliability
If a separate feedback receiver is used within the transmitter, then the transmitter operation can be adjusted, but the cost and power consumption increase
Solution Approach 1:
The patent combines the feedback receiver and main receiver into a single integrated receiver unit. This merging eliminates duplicate power consumption from having two separate receivers, while still maintaining the ability to adjust transmitter operation through the closed-loop feedback mechanism
Solution Approach 2:
The receiver performs multiple functions including primary signal reception and transmitter feedback, reducing the total power consumption by eliminating the need for a separate powered feedback receiver component
3Reliability
If a separate feedback receiver is used within the transmitter, then the transmitter operation can be adjusted, but the device complexity increases
Solution Approach 1:
The patent merges the feedback path with the existing receiver signal path, creating a unified closed-loop system. This integration reduces device complexity by eliminating separate feedback receiver components and their associated circuitry, while maintaining transmitter adjustability
Solution Approach 2:
The receiver is designed to handle multiple signal types and functions, serving as both the primary receiver and feedback receiver. This multi-functionality reduces overall device complexity by consolidating components rather than requiring separate dedicated units

AI summary
A method for operating an integrated transceiver, comprising coupling an operating transmitter and an operating receiver within the integrated wideband receiver, inputting a signal into the operating transmitter, performing a first conversion of the signal, wherein the signal is converted into a second signal, transmitting the second signal into the operating receiver, performing a second conversion of the signal, wherein the signal is converted into a third signal, transmitting the third signal into the operating transmitter, and adjusting the operating transmitter.
