MAXIMUM SWR:
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.
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.
Attenuation and SWR are tested as final electrical test.
