Product Detail

MA45471
Dual Anti-Parallel PIN Diode for MRI
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. 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.
