A focal plane imaging array receiver which covers the 90-115-GHz range for radio astronomical observations is described. The 3 × 5 array uses cryogenic Schottky diode mixers with integrated HEMT (high-electron mobility transistor) IF amplifiers. A cold, quasioptical filter selects the correct sideband, and terminates the image at 20 K. Polarization interleaving is used to minimize the array size on the sky. The array operates single sideband, with fixed tuned mixers. This is the first fully integrated millimeter-wave array receiver and also the first millimeter receiver to make extensive use of cooled optics.
