PSPL5510V Datasheet

PSPL5510V 60 GHz Attenuator


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.
