Theory of Series-Connected Distributed SIS Mixers with Ultra-Wide Instantaneous Bandwidth

Authors:
C.-Y. Edward Tong, Raymond Blundell
Abstract:
Series-connected distributed lumped element SIS mixers have emerged as a new generation of sensitive heterodyne submillimeter detectors which offer very wide instantaneous bandwidth. A formalism based on the transmission (ABCD) matrix is introduced to facilitate the simulation of this type of mixer with the Quantum 'Theory of Mixing. The simulations confirm that the IF bandwidth is very wide, up to at least 40 GHz. This agrees with our laboratory measurements in which good Y-factors are measured up to IF in excess of 20 GHz.
