Abstract
The IF bandwidth of an SIS mixer is limited by its capacitance. A series distributed design reduces the effective junction capacitance and the junctions can be reused as low impedance matching elements, limiting the capacitance of the RF matching network. In this paper, the analysis of this novel design is explored. Two receivers incorporating two types of series distributed SIS mixers were tested at 220 and 350 GHz. IF bandwidths of up to 16 GHz and low noise performance have been demonstrated.
