Programmable step attenuators aid ATE

A new line of intelligent programmable step attenuators come with built-in digital interfaces, designed to simplify the control and integration of these devices into subsystem and bench applications.

Aeroflex/Weinschel has developed a new line of intelligent programmable step attenuators with built-in digital interfaces, designed to simplify the control and integration of these devices into subsystem and bench applications.

The new programmable step attenuators are designed for use in automatic test equipment and OEM systems operating in the DC to 3GHz frequency range.

These models are available in many standard attenuation ranges and cell configurations.

Each cell contains a double-pole, double-throw relay that provides a minimum loss or attenuated path for the RF signal.

Microstrip circuitry and special compensation techniques produce flat attenuation/frequency characteristics.

The microstrip construction, using thick-film circuit elements, ensures product uniformity.

To minimise RF leakage, the 3200T Series attenuators are provided with gold-plated contact areas and feedthrough filters at each control terminal.

Features include: a wide selection of attenuation ranges and steps sizes; built-in TTLCMOS interface driver circuitry; high quality construction and connectors; and special configurations available on request.

Nominal impedance is 50ohm and the series is divided in two frequency ranges DC to 2.0GHz and DC to 3.0GHz.
