MicroWave Technology has released two pre-amplifiers for MRI (Magnetic Resonance Imaging) coil applications. The MSM series pre-amp is housed in a miniature package of 0.43 inch x 0.36 inch and has been developed for MRI coils with a large number of channels. Both pre-amplifiers are built using advanced low noise GaAs devices and components with very low magnetism, a critical requirement for MRI coil applications.
The MSM series pre-amp has a noise figure of 0.45 dB and a gain of 28 dB at 1.5T (64 MHz), 3T (123-128 MHz), and 7T (298 MHz) frequencies. It has an excellent linearity at 20 dBm IP3. It also has an impressive input power protection as high as 30 dBm. The MPE pre-amp is targeted at the low cost MRI coil market.
