RF programmable attenuators

9 June 2010 Telecoms, Datacoms, Wireless, IoT

Aeroflex’s new SmartStep line of intelligent programmable step attenuators with a built-in digital interface are designed to simplify the control and integration of these devices into subsystem and bench applications. They are designed for use in automatic test equipment and OEM systems operating in the DC to 6 GHz frequency range and offer a selection of attenuation ranges and step sizes: 0 to 55 dB in 1 dB steps; 0 to 103 dB in 1 dB steps; and 0 to 55,75 dB in 0,25 dB steps.

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 versus frequency characteristics. The microstrip construction, using thick-film circuit elements, ensures product uniformity. To minimise RF leakage, the 3400T series attenuators are provided with gold-plated contact areas and feed-through filters at each control terminal.
