MicroWave Technology, Inc., a division of IXYS Corp., announced that it released two pre-amplifiers for MRI (Magnetic Resonance Imaging) coil applications.
The MSM series pre-amp has a 0.45 dB noise figure and a 28 dB gain at 1.5T (64 MHz), 3T (123-128 MHz), and 7T (298 MHz) frequencies. It has an excellent linearity of 20 dBm IP3. The MSM pre-amp is in a miniature package of 0.43 x 0.36 inches. The MPE preamp is targeted for 3T (123-128 MHz) applications and it has a noise figure as low as 0.4 dB with a 27 dB gain and an excellent 20 dBm IP3. It also has an impressive input power protection as high as 30 dBm. Both pre-amplifiers are built using advanced low noise GaAs devices and components with very low magnetism, a critical requirement for MRI coil applications.
