Description
The 3200 Series Programmable Step Attenuators are
designed for use in automatic test equipment and OEM
systems operating in the dc to 3 GHz frequency range. This
series is available in many standard attenuation ranges and
cell configurations. Custom designed configurations are
available upon request. Each cell contains a double-pole,
double-throw relay that provides a zero path or attenu-
ated path for the RF signal.
Microstrip circuitry and special compensation techniques
produce flat attenuation versus frequency characteristics.
The microstrip construction, using thick-film circuit ele-
ments, ensures product uniformity. To minimize RF
leakage, the 3200 Series Attenuators are provided with
gold-plated contact areas and feedthrough filters at each
control terminal.
