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.

-55 °C to +125 °C

Storage Temperature

Junction Temperature

-55 °C to +125 °C

+175 °C

1. Operation of this device above any one of these parameters

may cause permanent damage.

Applications

2. Please refer to application note M538 for surface mounting

instructions

3. Total current per diode= I (rms) + I (dc) @ +25C

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.
