New data conversion technology enhances image quality of MRI systems

MRI (magnetic resonance imaging) scans provide extraordinarily clear images of the human body and are commonly used to diagnose a wide range of illnesses and injuries, such as Alzheimer’s disease, cancerous tumors, and torn ligaments. Analog Devices has introduced what it is describing as a breakthrough in data conversion that will be capable of giving clinicians and radiologists the much improved image clarity that they need to see smaller anatomical structures and abnormalities, such as breast cancer cells.

World's first JEITA RCX-2326 compliant MLCCs

Murata's GW new series of multilayer ceramic capacitors is the world's first to comply to the Japanese standard JEITA RCX-2326. This standard specifies capacitance under actual operating conditions including temperature and DC voltage. Murata has succeeded in achieving higher capacitance with the GW series under these conditions compared with previous models of multilayer ceramic capacitors. The GW series is suitable for decoupling capacitor use in power supply circuits for low voltage driven devices and CPUs, FPGAs and similar applications.

STMicroelectronics unveils innovative plastic air-cavity packaging

STMicroelectronics has unveiled an innovative plastic air-cavity package that could enable high-power transistors for Radio-Frequency (RF) applications such as transceivers, broadcast equipment and MRI scanners to deliver performance and cost advantages over alternative devices in ceramic packages.

Air-cavity packages provide high electrical isolation for silicon die, and are well suited for high-frequency, high-power applications. Whereas the traditional package body is typically ceramic, to withstand high-temperature soldering during package assembly, this new air-cavity technology now enables lower thermal resistance, lower weight, and reduced cost compared to devices in ceramic packages.
