RF Direct Sampling for enhanced performance and scalability

Recent advancements in data converter technologies have significantly increased sampling rates, enabling the potential achievement of bandwidths up to several tens of gigahertz for the latest ADCs and DACs. This progress has paved the way for applications involving RF digitization, employing the intermediate frequency (IF) sampling technique.

Here, the analog signal undergoes conversion to a lower intermediate frequency before being sampled by a converter. With the rise in sampling rates, direct sampling of RF signals without additional RF conversion stages has become feasible, even for signals in the tens of gigahertz range.

Referred to as direct sampling, this approach is now applicable across various radar and EW frequency bands, including the Ku, K, and Ka bands. Implementing the RF direct sampling method can streamline architectures and improve equipment flexibility, scalability, and SWAP-C (Size, Weight, Power, and Cost).

apissys, an expert in wideband conversion solutions, is dedicated to designing products leveraging cutting-edge technology to offer direct sampling capabilities for radar and electronic warfare applications.
