MicroWave Technology, Inc. a division of IXYS Corporation released two pre-amplifiers for MRI 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.
“The MSM series pre-amp is housed in a miniature package of 0.43 inch × 0.36 inch and will be an ideal choice for MRI coils with a large number of channels. The MPE pre-amp is targeted at the low cost MRI coil market while still maintaining excellent RF performance,” said Dr. Greg Zhou, the General Manager of Microwave Technology, Inc. “These two pre-amplifiers are the newest additions to our pre-amp product family. As a major pre-amplifier supplier to major MRI equipment manufacturers in the past 15 years, we are committed to support our medical equipment customers so they can meet their latest requirements.”
