LOW NOISE MILLIMETER DETECTOR

Abstract

Work conducted on the design and development of 2-millimeter wavelength circular guide point contact detectors is summarized in this report. Circular waveguide formed the basis of the 2 millimeter detector design after preliminary comparison with existing rectangular waveguide de tectors at 4- millimeter wavelengths. A waveguide diameter of 0.090 in., with a dumb bell type of adjustable shorting plunger was found to give the best performance. Test results of tangential signal, figure of merit and conversion loss is reported. Results indicate that a 2-mm video detector can be fabricated with a -35 dbm tangential signal sensitivity at 10 uA bd 1 mc video band width. Calculations of the mini mum detectable signal, MDS, from figure of merit measurements indicate the goal of a minimum detectable signal of 10 to the - 10th power watts was met. A harmonic generator and a calibrated 2-mm attenuator were constructed. The report contains design data for these components, and the results obtained from their use.
