In this paper, we present the design and measurements of a 90 GHz prototype of a millimeter-wave channelizing spectrometer realized in rectangular waveguide for astronomical instrumentation. The device was fabricated using conventional high-precision metal machining, and the spectrometer can be tiled into a 2D array to fill the focal plane of a telescope.(More)
We discuss the design, fabrication, and testing of prototype horn-coupled, lumped-element kinetic inductance detectors (LEKIDs) designed for cosmic microwave background studies. The LEKIDs are made from a thin aluminum film deposited on a silicon wafer and patterned using standard photolithographic techniques at STAR Cryoelectronics, a commercial device(More)
We present the design concept and our latest simulation results for a novel low (R~100) to moderate (R~1000) resolution multi-pixel direct detection spectrometer operating at millimeter (mm) and submillimeter (submm) wavelengths. This design implements a transmission line filter bank using rectangular waveguide resonant cavities as a series of frequency(More)
