• Manufacturer Part Number: sna-686
• Description: Dc-6 Ghz Cascadable Gaas Mmic Amplifier
• Manufacturer: Sirenza Microdevices

303 S. Technology Ct., Broomfield, CO 80021
NOTE: While the SNA-686 can be operated at different bias currents, 65 mA is the recommended bias for
lower junction temperature and longer life. This reflects typical operating conditions which we have found
to be an optimal balance between high IP3 and MTTF. In general, MTTF is improved to more than 100,000
hours when biasing at 65 mA and operating up to 85°C ambient temperature.
