Revision Date: 10/15/2010
The Aeroex / Metelics MSS20,000 series of Schottky
diodes is fabricated on P-Type epitaxial substrates for
superior 1/f noise performance in microwave zero-bias
detector applications up to 40 GHz.
• Very low 1/f Noise
• Detector applications to 40 GHz
• Chip, beam lead or packaged devices
