MAXIMUM DEVIATION OVER FREQUENCY:
NOTE: All dimensions are given in mm (inches) and are maximum,
unless otherwise specified.
Screening
Units are screened 100% as follows:
Thermal Shock:
10 cycles, -55°C to +100°C
Peak Power:
500 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.
