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. Applications The MA44781 Device is well suited for MRI Passive switching applications. The PIN Diodes become high Q, R-C elements under small signal and behave as effective passive rectifiers or short circuits 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. 1. Operation of this device above any one of these parameters may cause permanent damage. 2.
