Abstract
In the framework of a ground-based cloud profiling radar at 94 GHz and a 3-D high-resolution imaging radar at 300 GHz developed at the Universidad Politécnica de Madrid, signal sources based on generation by direct digital synthesis, power amplification and frequency multiplication are designed. This work focuses on the last frequency multiplication stage of the source chain of both systems. The design of frequency triplers at 94 GHz and 300 GHz based on Schottky diode technology is reported. For the cloud profiling radar, the simulated room-temperature performance of the designed 94 GHz frequency tripler shows a conversion efficiency of around 11% in the 90-98 GHz frequency band for an input power of 100 mW, with a 3-dB bandwidth from 75 to 102 GHz. For the imaging radar, the simulated room-temperature performance of the designed 300 GHz frequency tripler predicts over 2% of conversion efficiency between 260 and 300 GHz for an input power of 100 mW
