Point Contact Diodes:
1N Series
X Band Point Contact Mixer Diodes
Description
This
MicroMetrics
1N series of Point
Contact Mixer diodes is designed for
applications through X-Band. These
diodes employ epitaxial silicon
optimized for low noise figure and
wide bandwidth and are specifically
designed for use in stripline, microstrip
and coaxial environments. Each
device in this series is in an axial lead
glass package.
Applications
This 1N series of Point Contact Mixers
is suitable for use in waveguide,
coaxial and stripline applications.
Features
• Mechanical Reliability
• Low Noise Figure
• Wide Bandwidth
