Richardson RFPD offers design assistance for component used in the radio frequency (RF) section of any MRI system or sub-system. We maintain a complete line of RF semiconductors for MRI systems—commercial grade, high reliability, discrete (diodes, transistors), and integrated (power amplifiers, digital attenuators). In addition, we supply all of the necessary passive RF components needed, including tuning capacitors, tuning inductors, cables, connectors, fixed RF capacitors, couplers, combiners, heat sinks, gaskets, filters and resistors. Please browse our MRI product categories, below, as well as the application notes and white papers included in the Technical Resources section. And please do not hesitate to contact us for design assistance. | |

Richardson RFPD employs more RF engineers than any global distributor. By offering deep technical expertise to support the latest products from the leading suppliers in RF & Wireless and Energy Technologies, we are uniquely positioned to help customers meet the challenges of changing markets.
A Magnetic Resonance Imaging (MRI) System is designed to “see” inside a given object or tissue sample (living or dead), and produce an image that represents, as closely as practical, how the object or sample really looks on the inside. MRI techniques are commonly used for medical diagnoses, materials research, and newer industrial applications (e.g., test food quality, test timber quality, rock permeability). An MRI machine uses a combination of one large stationary magnet, three directional and precisely controlled electro-magnetic coils (gradient coils), an RF pulse generator, RF detector, and the properties of elemental nuclear magnetism.
For more detailed information on MRIs, their uses, and the RF sections of an MRI system, please refer to the technical articles and design considerations found in the Technical Resources tab, including:
