The MADP-011048 acts as a passive switch using silicon PIN diodes in a non-magnetic surface mount package. There are two sets of diode pairs constructed in an anti-parallel configuration that operate from 5 to 400 MHz.
The two pairs of diodes are arranged in an electrically isolated anti-parallel configuration. The diode pair with anode on Pin 1 and cathode on Pin 6 will be referenced as D1 and the diode pair with anode on Pin 5 and cathode on Pin 2 will be referenced as D2.
The MADP-011048 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 configuration provides efficient power handling.
