Liu, X. (author)This master thesis demonstrates the realization of a 2×2 heterodyne receiver array at 1.4 THz based on superconducting hot electron bolometer (HEB) mixers and a Fourier phase grating local oscillator (LO). This is the first time to build a heterodyne receiver array based on these two techniques at such a high frequency. The theoretical knowledge...master thesis 2015

Peters, R.Y. (author), Liu, X. (author)In tegenstelling tot conventionele radar -en radiosystemen kan de toepas- sing van een Software Defined Radio (SDR) grotendeels bepaald worden in software. Een SDR bestaat uit een RF-frontend, een paar ADC/DAC’s, een FPGA en een host computer. In de hostcomputer en de FPGA kan de functie van een SDR volledig worden geherdefini ?eerd, zonder dat...bachelor thesis 2011
