    Struggling with receiver performance despite advanced processing? Your system’s bottleneck might be hiding in the often-overlooked RF stage1, limiting your overall potential and final results. The RF stage1 selects the desired radio frequency signal from the antenna, amplifies it to a usable level, and filters out unwanted noise and interference. This initial processing is crucial for determining the overall sensitivity and quality of the entire receiver system. I once saw this firsthand. We were working on a complex radar system, and my colleague, a brilliant PhD from MIT, was pushing the limits of baseband processing2. He introduced AI and GPU parallel processing, but we still couldn’t hit our performance targets.
