Dual RF Channel Amplifier Layout With Shared Telemetry Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing linearizer-channel amplifier devices for satellite RF systems require a large number of components and significant space and production costs due to the need for multiple independent modules for each RF channel, which complicates the architecture and increases expenses.
Innovation Solution
A dual RF channel linearizer-channel amplifier device is designed with two independent radiofrequency channels sharing a single remote control and telemetry module, which provides routing and management for both channels, reducing the number of components and space requirements through a common communication bus and shared electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each RF channel uses a dedicated linearizer-channel amplifier device with independent modules, then channel independence and control are maintained, but space requirement and production cost increase significantly
Solution Approach 1:
The patent combines two RF channel amplifier devices into a single integrated device, where two channel-amplifier modules share common components including the housing, remote control and telemetry module, and power supply system. This merging reduces the overall space requirement while maintaining independent operation of each RF channel through separate amplifier modules within the shared structure.
Solution Approach 2:
The remote control and telemetry module serves as a universal component that manages both RF channels simultaneously. This multi-functional module handles control signals and telemetry data for both channels, eliminating the need for separate control modules and reducing the overall component count while maintaining full independence of channel operations.
2Ease of operation
If each RF channel uses a dedicated linearizer-channel amplifier device with independent modules, then channel control is maintained, but production cost increases
Solution Approach 1:
By merging two channel-amplifier modules into a single device with shared components (housing, control module, power supply), the patent reduces the total number of discrete units that need to be manufactured, tested, and assembled. This consolidation lowers production costs while maintaining the ability to independently control each channel through the shared remote control module.
Solution Approach 2:
The universal remote control and telemetry module is designed to manage multiple RF channels simultaneously, reducing the need for multiple identical control systems. This multi-functional approach decreases component redundancy and production complexity while preserving full operational control over each individual channel.
3Ease of operation
If multiple independent modules are used for each RF channel, then channel management is simplified, but device complexity increases
Solution Approach 1:
The patent merges multiple functional modules into a unified device structure where two channel-amplifier modules share common infrastructure including housing, control systems, and power supply. This consolidation reduces the total number of discrete components and interconnections while maintaining simplified channel management through the integrated remote control module that handles both channels.

AI summary
A linearizer-channel amplifier device for a dual RF channel designed to be installed on a telecommunication satellite comprises two independent radiofrequency channels, each radiofrequency channel corresponding to a radiofrequency-signal communication channel and comprising a channel-amplifier module, the two radiofrequency channels being connected to one and the same remote control and telemetry module designed to route and to manage remote control signals dedicated to each of the two channel-amplifier modules and to manage telemetries produced by the two channel-amplifier modules. For application notably to the field of satellite telecommunications and in particular to the radiofrequency transmission systems of satellite repeaters.
