| Popis: | A complete radiometer simulation framework with special emphasis on high frequencies and switched system performance is proposed. The simulation procedures have been tested on a system configuration used in a branch of the 30-GHz Planck Radiometer, which detects radiation from the cosmic microwave background in a window with 20% relative bandwidth centered at 30 GHz. The goal of the article is not to obtain detailed conclusions about this radiometer in particular but to test the viability of proposed techniques in a realistic context. Basic RF performance of an ideal and a more realistic version of the radiometer is compared. Furthermore, the whole system simulation is implemented in the frequency domain and the time domain, on the same platform that is used to design separate microwave components, introducing realistic parameters for the high-frequency components, such us measured S parameters of the amplifiers and measured current-voltage characteristics of the detectors. |
