STEVAL-IMR002V1：2 kW/100 V RF demonstration board for 3 T MRI based on the STAC4932B
The STEVAL-IMR002V1 demonstration board is based on the new generation of high voltage DMOS products housed in the STAC® air cavity package and capable of delivering an output power up to 1.2 kW for industrial, scientific, and medical applications such as 1.5 T and 3 T magnetic resonance imaging (MRI).
This new air-cavity technology now enables lower thermal resistance, lower weight, and reduced cost compared to devices in ceramic packages.
The STEVAL-IMR002V1 demonstration board implements the design of a 2 kW-100 V, 123 MHz Class AB peak power amplifier (PPA) for 3 Tesla MRI applications.
It uses double push-pull bolt-down devices, two STAC4932B - N-channel MOSFETs, capable of exceeding 2000 W @ 123 MHz with large signal gain of 19 dB in Class AB and a drain efficiency of 60%.
It almost doubles the output power of previous amplifiers using MOSFET transistors in standard ceramic packages.
