CryoCircuits LNPA Series Low-Noise MRI RF PreAmp - Scale Comparison Photo

The LNPA series are ultra-low-noise, low input impedance RF preamplifiers covering a range of MRI frequencies. They are an ideal choice for multiple RF coil arrays providing decoupling between channels. Multiple RF coil arrays are becoming a necessity for high-end MRI scanners, providing speed and performance advantages. The exceptionally low noise figures of the LNPA series provide ultra sensitivity for spectroscopy applications and low-loss cryogenic RF probes. The LNPA123M-001 is a 123 MHz preamplifier targeted for 3T proton imaging. Typical specifications are given below.
