Paper Abstract

A model is developed to study SiC-based IMPATTs to operate at D-band frequency and the device properties of 3C, 4H, 6H-SiC based SDR IMPATTs are compared at the same operating conditions and frequency of operations. A noise analysis model is also developed to compare the noise characteristics of 3C, 4H and 6H SiC-based SDR IMPATTs. The results show that 3C-SiC based SDR IMPATTs have better power delivery capability whereas 4H SiC-based SDR IMPATTs are less noisy. When a power noise tradeoff consider, it is seen that 4H SiC-based SDR IMPATTs have better Noise Measure than the other two polytypes. These results can be used as the first hand information by the experimentalist.
