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 standard TO-5

type double-pole, double-throw relay that provides a

zero path or attenuated 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.
