Abstract

We report the design of a 230 GHz dual-polarization (2-pol) balanced Superconductor-Insulator-Superconductor (SIS) receiver that can be easily extended for large array applications. We achieve this by integrating all of the required radio frequency (RF) and local oscillator (LO) components on-chip using planar superconducting circuit technology, therefore simplifying the architecture of the receiver block substantially. One major feature of our design is the planar LO injection scheme, which couples the LO with a single on-chip antenna and distributes the LO power via a series of microstrip couplers to the balanced mixers of each polarization of each pixel. In this paper, we describe in detail the design and layout of the individual planar circuit components of our receiver, as well as how they are integrated to form a full receiver. We then conclude the paper with the design of a 2-pixel array demonstrator, illustrating how the balanced SIS mixer and the LO distribution network can be extended to form an even larger array.
