Compact Dual-Polarization Schottky Barrier Diode Receivers for Submillimeter Wave Remote Sensing

Anders Emrich, Jan Stake, Olivier Auriacombe, Peter J. Sobis, Vladimir Drakinskiy

Co-optimized orthogonal E-field probes and subharmonic Schottky mixers deliver compact dual-polarization receivers with up to 34 dB isolation and 833 K noise temperature.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the integrated dualpolarization receiver topology achieves excellent sensitivity in a highly compact package, offering an efficient and scalable solution for polarimetric applications in submillimeter-wave remote sensing

C2weakest assumption

The co-optimization and integration of the two orthogonal E-field probes with the subharmonic mixers does not introduce unaccounted losses, coupling, or fabrication variations that would degrade the reported isolation and noise performance in operational environments. (Abstract description of co-optimized integration and measured results)

C3one line summary

Compact dual-polarization Schottky barrier diode receivers at 315-650 GHz achieve up to 34 dB cross-polarization isolation, DSB noise temperatures down to 833 K, and Allan stability over 10 s in a single module with shared components.
