MA45471 Dual Anti-Parallel Non-Magnetic PIN Diode RoHS Compliant Features • • • • • Designed for MRI applications Anti-Parallel Self Bias Arrangement Non-Magnetic Surface Mount Package SPC Process for Superior Parametric Repeatability RoHS Compliant with 260°C reflow compatibility Description The MA45471 device acts as a passive switch using silicon PIN diodes in a surface mount non– magnetic package. The PIN diode pair are arranged in an anti-parallel configuration and encapsulated with a non conductive epoxy resin. Applications The MA45471 is well suited for MRI Passive switching applications. The PIN diodes become a high Q, R-C network under small signal and behave as an effective passive rectifier or short circuit under high RF Signal to tune and de-tune the resonant MRI tank circuit. The anti-parallel arrangement provides for more efficient RF power handling.
