MRI certified LNAs

Other Parts Discussed in Thread: TL5500

Hello,

Are there any LNAs certified non-magnetic that can be used for NMR/MRI applications?

freq range: 125M- 500MHz of ~micro volt input signal

size: less than 5mmx5mm

gain: ~20dB or higher

I saw that there was an LNA certified to be non-magnetic (TL5500) but it doesn't seem to be in stock in most places. Is there a replacement/newer model of this part??

Thank you so much!

    Kota, 

    Thanks for looking at TI products! TL5500 is still the best for MRI LNA up to date. This is a niche product  with a small customer basis. So  it is more like stock on confirmed orders only.

    you may look at some high speed amplifiers which can support the required BW and gain. Thanks!
