NOTE: All dimensions are given in mm (inches) and are maximum,
unless otherwise specified.
FREQUENCY RANGE:
dc to 32.0 GHz
Screening
Units are screened 100% as follows:
MAXIMUM DEVIATION OVER FREQUENCY:
Thermal Shock: 10 cycles, -55°C to +100°C
Nominal ATTN (dB)
Deviation (dB)
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.
