MRI diode protects MRI receivers from high RF energy fields
RICHARDSON RFPD Macom MADP-009989 diode protects MRI receivers from high RF energy fields, including long RF pulses and RF spike pulses present in most MRI machines. Device acts as a passive protector (limiter) for the MRI receiver. No forward bias voltage is required to turn-on the diode. It is self-biased by the RF transmitter pulse power. A switch driver is not needed for this receiver protection application. Device is available in two package configurations for design flexibility.
