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.
