The paper deals with a new technique for deviation of atherosclerotic plaque. There are two plaque types: The yellow and white plaque. The white plaque is hard, fibrous and dimensionally stable. The yellow plaque is soft with high-cholesterol ratio and dimensionally instable. Every hit with a medical tool can generate a critical medical case, because the plaque can be rapture and the plaque particles could cause in a stroke. A catheter with a BiCMOS microwave sensor was developed in the latest research. For a stable function and a high reliability a suitable electronic packaging has to be fulfill. The development starting with the sensor design up to a complete electronic packaging which allows a measurement in different liquids and tissues is discussed in this paper.
