RF Up/Down-Converter Design using GNU Radio and SDRs
Introduction
The RF Up/Down-Converter project is a robust system designed to efficiently convert signals between different frequency bands using GNU Radio and Software Defined Radios (SDRs). This versatile tool seamlessly performs both up-conversion (C/Ku to L band) and down-conversion (L to C/Ku band), catering to diverse communication needs.
Objective
Our primary goal is to develop a portable and user-friendly RF converter capable of:
- Enabling seamless signal conversion between C/Ku and L bands.
- Implementing adaptable sampling rate mechanisms for efficient conversion.
- Ensuring data security during transmission by incorporating robust security measures.
- Offering an intuitive interface for easy operation across various communication systems.
- Facilitating versatile applications including satellite communication, real-time monitoring, military, and security sectors.
