Description
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.
