40GHz Attenuator
PSPL5510K Datasheet
The PSPL5510K 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 2.92
mm attenuators have 5 ps risetimes and are recommended
for measuring pulses with risetimes of 15 ps or slower. They
are ideal for use with PSPL's Model 4015C, 15 ps pulse
generator. For frequency domain measurements, the useful frequency range is DC to 40 GHz.
The 2.92 mm connector is compatible with SMA and 3.5 mm connectors.
