MWT releases pre-amps for MRI applications

Advanced low noise GaAs-based devices feature very low magnetism

MicroWave Technology (MwT), a division of Ixys, has released two pre-amplifiers for MRI (Magnetic Resonance Imaging) coil applications. Both pre-amps 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 0.45dB noise figure and a 28dB gain at 1.5T (64 MHz), 3T (123-128 MHz), and 7T (298 MHz) frequencies. It has an excellent linearity of 20dBm 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 0.4dB with a 27dB gain and an excellent 20 dBm IP3. It also has an input power protection as high as 30dBm.

"The MSM series pre-amp is housed in a miniature package of 0.43 inch x 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 Greg Zhou, 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."

Based in Fremont, California, MwT makes RF and microwave frequency discrete semiconductor products, advanced MMICs, hybrid modules, and amplifiers for wireless communication, military/aerospace, industrial, and medical applications. MwT houses one of four Ixys fab facilities, offering a factory specialising in GaAs-based semiconductor and hybrid microwave integrated circuitry (HMIC) manufacturing.
