WMA Series SMT Magnetic Radio Imaging (MRI) Pre-Amplifiers

WMA series miniature low noise amplifiers are designed for growing demand in MRI pre-amplifer multiple chanels applications. The pre-amplifiers have as low as 0.5 Ohm imput impedance with unconditional stable design. The noise figure is 0.50 dB or lower and the reverse isolation as high as 70 dB.
