Screening
MAXIMUM DEVIATION OVER FREQUENCY:
Units are screened 100% as follows:
Nominal
Deviation (dB)
Monitored Thermal Cycle: Units are subjected to 10
thermal cycles between -55 °C to +100 °C. The PIN-to-PIN
DC resistance is continuously monitored and stored.
Peak Power: 200 Watts, 5 μsec pulse width; 0.05% duty
cycle for 3 minutes at each end. DC Attenuation is
measured before and after peak power.
Attenuation and SWR are tested as final electrical test.
