The process of converting analog radio signals to digital ones has traditionally required several analog and electronic components that can cause latency and interference issues. Direct RF has emerged as a processing concept to remove latency and interference risks by providing a new type of connection between these analog and digital worlds. Next-generation direct RF technology removes the need for some of the analog RF translation stages required by legacy data converters that are limited by the giga samples per second they can sample and the range of signal frequencies and bandwidths they can manage. This 60-minute webinar from the editors of Aerospace & Defense Technology will demonstrate how the aerospace and defense industry can leverage the use of direct RF technology to redefine the capabilities of radar, software-defined radios, jamming, and other RF and microwave systems.
Topics include:
- Dynamic range versus sample rate and input frequency
- Interleaving errors and artifacts
- Multi-channel and phased array considerations
- Testing of wideband ADCs
- Challenges of getting enough dynamic range with wideband ADCs
- Difficulty of dealing with large datasets — moving, processing, and storage of high bandwidth signals
- Need for front-end preselection to avoid large signal overloading of the ADC and obscuring co-located small signals
- Forward-looking developments
An audience Q&A session will follow the technical presentation.
