WMAS Series SMT Version, Superconductor-like MRI Pre-Amplifiers
|
WMAS Series Room Temperature Superconductor-like MRI Pre-Amplifiers
WMAS series room temperature superconductor-like preamps are designed for ultimate SNR MRI multiple chanel coils applications. The noise figure at room temperature reaches 0.25 dB or lower and the reverse isolation can be as high as 70 dB. The pre-amplifiers have as low as 0.5 Ohm input impedance with unconditional stable.
