Studies on Impatt Diodes, as the premier class of Solid State Power Sources covering frequencies from 10 to 500 GHz, reveal various ways and means for pushing Frequency, Power and Efficiency and lowering avalanche noise through monitoring of Structural, material and operating parameters. Enhancement of efficiency through incorporation of charge bump, choice of WBG semiconductor like ZnS, use of new structure (DAR) and new junction type (Hetero junction/Hetero structure junction; pushing rf power by increasing bias current, using different WBG semiconductors (SiC, GaN, ZnS); moving to high frequency band through increase of bias current with doping modulation for compensating performance deterioration, harmonic operation and width modulation and lowering of noise by selection of proper semiconductor, diode structure and type of junction can be realized.
