WMM series miniature 6-pin low noise amplifiers are designed for growing demand in MRI pre-amplifer multiple channels applications. The pre-amplifiers preserve the low input impedance with unconditional stable design. The noise figure is 0.50 dB or lower and the reverse isolation as high as 65 dB.The modules have 6 pins and very easy for a customer to install.
