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.

Internal Construction

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.
