DSC Newsletter - Space Qualified InGaAs Quad PD + TIA Photoreceivers

  

Ewing, NJ - June, 2020

We introduce 1 mm, 1.5 mm, and 2 mm diameter InGaAs Quad PD + TIA photoreceivers with low capacitance and ultra-low noise performance for several space-based applications. These devices have been comprehensively tested for radiation environment that includes High Energy Protons, Gammas, and constituent elements of Galactic Cosmic Rays (GCR). At present these devices are available in TO-3 package.
