DESCRIPTION

· The MA44781 is a passive switch utilizing silicon PIN diodes in a surface mount package.
· It features two sets of PIN diode pairs in opposing configurations.
· The package is sealed with non-conductive epoxy resin, suitable for surface mount applications.
· Ideal for MRI passive switching, it functions as a high Q, R-C network under small signals and as an effective passive rectifier or short circuit under high RF signals.

FEATURES

· Specifically designed for MRI applications.
· Features an anti-parallel self-bias arrangement.
· Comes in a non-magnetic surface mount package.
· Utilizes SPC process for superior parametric repeatability.
· RoHS compliant and compatible with 260°C reflow.

APPLICATIONS

· Primarily used in MRI systems for passive switching.
· Effective in tuning and de-tuning the resonant MRI tank circuit.
· The anti-parallel doublet arrangement enhances RF power handling efficiency.
