This presentation is concerned with the experimental evidence that proves technical feasibility of the hybrid planar integration (HPI) scheme proposed previously to construct SIS mixer focal plane arrays of unprecedented compactness. The scheme is characterized by the adoption of silicon membrane-based waveguide probes, which allows superconducting monolithic microwave integrated circuits (MMICs) to couple signal and LO from CNC-machined waveguides through multiple paths. A 2 x 2 dual-polarization balanced SIS mixer array has been implemented with this scheme and assessed at 2 mm wavelengths. This compact array has demonstrated uniform LO distribution and low crosstalk between pixels. The RF performance of component pixels has been confirmed to be little affected by the high degree integration. The potential implementation of the HPI scheme at THz frequencies is also discussed.
