RF Power plays a role in the Medical Industry that requires high precision RF power measurement. Most major manufacturers of Magnetic Resonance Imaging (MRI) machines purchase Bird equipment for the research and development and field calibration of their MRI’s. Bird’s unique capabilities have enabled the design and manufacture of products capable of handling the very high specific peak power pulses. These products have been combined into a variety of calibration kits that include custom power sensors and custom RF loads designed specifically for each type of MRI.
