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.
1. Operation of this device above any one of these parameters
may cause permanent damage.
