A 15 ELEMENT IMAGING ARRAY FOR 100 GHZ

A focal plane imaging array receiver is described which covers the 90-115 GHz range for radio astronomical observations. The 3x5 array uses cryogenic Schottky diode mixers with integrated HEMT IF amplifiers. A cold quasi-ptical filter selects the correct sideband, and terminates the image at 20 K. Polarization interleaving is used to minimize the array size on the sky.
