The purpose of the investigation was to study the potentialities of magnetic resonance imaging (MRI) in the diagnosis of knee joint sarcomas. The paper presents the results of examining 13 patients of different age, shows the potentialities of the technique in the identification of knee joint sarcomas, and describes the MRI semiotics of sarcomas in both the(More)
A 32V LDMOS technology with all gold metallization optimized for pulsed applications has been used to design a 130W discrete power transistor matched over the 2.7–3.5 GHz instantaneous frequency band, covering both commercial and military radar markets. The high power device, operated in class AB bias, with a 300us and 10% duty cycle pulse signal(More)
