The MS8520-48 is low barrier, N-type, silicon Schottky
diode designed for applications in microwave mixers and
detectors at frequencies from below 100 MHz to
beyond 40 GHz.
Maximum Ratings
Incident Power
+20 dBm @ 25°C
Reverse Voltage
3V
Forward Current
10 mA @ 25°C
Power Dissipation
50 mW @ 25°C
Operating Temperature
-65°C to +150°C
Storage Temperature
-65°C to +150°C
These Schottky diodes are packaged in the newly
developed ultra-low capacitance M48 package that has
shown improved sensitivity in Doppler Transceiver
mixer/detector mounts at 24 GHz.
Microsemi’s vertical offset chip bond pad design
allows rotational symmetry in a waveguide mount and
rugged bonding to the top contact without damage to the
junction. MSC’s semiconductor process also results in
a low 1/F noise device with low specified RS and CJ
values.
