RoHS CompliantGENERAL DESCRIPTION
KEYFEATURES
There are two principle applications for which the GC47733‐192AP modules are intended: 1) MRI receiver protection from high RF energy fields, including long RF pulses and RF spike pulses present in most MRI machines. The diode assembly exhibits extremely low insertion loss, both in the “on” state (high power present) and the “off” state (receiver power present) so the Receiver’s Noise Figure is not increased by the protector circuit. 2) Passive switching of surface coil detuning and blocking circuits. In this case, the flow of loop current during transmitter pulse turns on the diodes, without a switch driver. Manufacture of dual anti‐parallel pairs of GC47733‐192AP’s ensures that the matched pair of diodes can be inserted in a coil with the correct diode polarities and with the minimum parasitic inductance and capacitance, thermal impedance and labor for the coil manufacturer.● Low magnetic construction
