RF Router Automatic Gain Control Signal Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF routers experience signal distortions and blocking, especially with high power RF signals, necessitating an improvement in RF routing systems to reduce these disadvantages.
Innovation Solution
A radio frequency (RF) router system is designed with a controller, input stage, intermediate stage, and output stage, featuring processors and switch matrices that adjust power levels of RF signals using automatic gain control (AGC) to compensate for signal processing and maintain optimal power levels, thereby reducing signal distortions and blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional RF routers are used to route high power RF signals, then signal routing functionality is provided, but signal distortions and blocking occur
Solution Approach 1:
The input processor performs preliminary action by adjusting the power level of incoming RF signals before they enter the routing stage. This pre-adjustment prevents signal distortions and blocking from occurring during routing, thereby improving signal routing reliability while eliminating harmful effects.
Solution Approach 2:
The system implements feedback by monitoring the power level of RF signals and using this information to control the input and output processors. This closed-loop control ensures signals maintain optimal power levels throughout routing, preventing distortions and blocking while ensuring reliable signal transmission.
2Object-affected harmful factors
If power level adjustment is implemented in the RF router, then signal distortion is reduced, but device complexity increases
Solution Approach 1:
The system applies local quality by implementing power level adjustment only at specific locations (input and output stages) rather than throughout the entire routing path. This targeted approach reduces signal distortion at critical points while minimizing the addition of complex components to the overall router structure.
Solution Approach 2:
The input and output processors change parameters by adjusting power levels of RF signals dynamically. This parameter adjustment reduces signal distortion without requiring fundamental changes to the router's core architecture, thereby limiting the increase in device complexity while achieving the desired improvement in signal quality.

AI summary
Various embodiments are described herein for a radio frequency (RF) signal router. In one example embodiment, the RF router comprises a controller, an input stage, an intermediate stage and an output stage. The input stage includes RF input terminals, pre-processing circuit and input processors, where each RF input terminal receives an incoming RF signal, each pre-processing circuit processes the incoming RF signal based on its power level, and each input processor adjusts a power level of an input RF signal based on a first controller signal to generate a processed input RF signal. The intermediate stage comprises intermediate switch matrices coupled to a controller and input processors, and configured to route intermediate RF signals. The output stage comprises output processors coupled to the controller, where each output processor is configured to adjust a power level of an output RF signal based on a second controller signal and generate a processed output RF signal, and where the second controller signal corresponds to the first controller signal.
