60 GHz Attenuator
PSPL5510V Datasheet
The PSPL5510V Attenuators address a need that has been
totally ignored by other microwave component manufacturers
who specify their products in the frequency domain, but
ignore the time domain responses. For time domain
measurements, it is important to also know the transient
response of attenuators used in a test set-up. These 1.85
mm attenuators have 5 ps rise times and are recommended
for measuring pulses with rise times of 13 ps or slower. For
frequency domain measurements, the useful frequency
range is DC to 60 GHz. The 1.85 mm connector is compatible with 2.4 mm connectors.
