MA44781
Dual Pair Anti-Parallel Non-Magnetic PIN Diode
Features
 Designed for MRI Applications
 Anti-Parallel Self Bias Arrangement
 Non-Magnetic Surface Mount Package
 SPC Process for Superior Parametric
Repeatability
 RoHS* Compliant and 260°C Reflow Compatible
Description
The MA44781 device acts as a passive switch using
silicon PIN diodes in a surface mount package.
There are two sets of two PIN diode pairs
constructed in opposing configurations. The package
is sealed with a non-conductive epoxy resin and is
suitable for surface mount applications.
The MA44781 device 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 doublet arrangement
provides for more efficient RF power handling.
