Converting the Challenges of a Faster-Moving World.
Today’s system designers working in communication infrastructure, instrumentation, as well as aerospace and defense are faced with complex challenges to meet increasing bandwidth demands in a progressively congested frequency spectrum. Frequency planning compromises—along with size, weight, power, and performance requirements—increase signal chain complexity as the system operation moves from the RF to the mm-Wave spectrum domain and bandwidth demands move from megahertz to gigahertz. The ability to utilize more of the frequency spectrum enables new system capabilities and features to create a better user experience, but it places greater emphasis on software development. Explore how our RF Converter Solutions help to solve these complex challenges.
RF Converters Enable Efficient Multiband Radios for Next-Generation Wireless Base Stations
Cellular bands have increased 10x, while data converter sample rates have increased 100x. Where does this leave the infrastructure base station?
RF Converters: A Technology That Is Enabling Wideband Radios
This article takes a look at how RF converters can now deliver on the promise of wideband radios, dramatically reducing the hardware needed to create a radio, and enabling a new level of reconfigurability via software.
Wide Bandwidth and High-Dynamic Range
The wide bandwidth of our gigahertz RF converters lets you capture or synthesize the entire frequency spectrum at once. That simplifies hardware design by reducing the number of frequency translation stages and relaxing filter requirements. High-dynamic range and superior noise performance also enables the use of higher-order modulation encoding schemes to improve information throughput. All of which means there’s more to work within the digital domain.
Integrated Digital Signal Processing
Integrated digital signal processing supports software-defined platforms by shifting frequency translation and filtering designs from the analog-domain to the digital-domain. That gives you a higher level of scalability and flexibility in frequency tuning that you simply cannot get with fixed hardware signal chains. As a result, you adapt and re-configure platforms to avoid obsolescence and meet the demands of ever changing markets.
Enabling the Transition to Software-Defined Platforms
The increasing demands for advanced capabilities, lower costs, and faster time to market all point to a software solution. The combination of high-performance analog and digital signal processing found in ADI RF converters are designed to support the evolution of software-defined platforms. That can be an essential building block to capitalizing on market opportunities and maximizing product lifecycles in Aerospace & Defense, Communications, and Instrumentation.
