Programmable attenuators are
easy to integrate
Intelligent programmable step attenuators feature a built-in digital interface designed to simplify the control and integration of these devices into subsystem and bench applications
Aeroflex/Weinschel manufactures a line of intelligent programmable step attenuators with a built-in digital interface designed to simplify the control and integration of these devices into subsystem and bench applications. This series of programmable step attenuators is designed for use in automatic test equipment and OEM systems operating in the DC to 6GHz frequency range.

Relay range adds low-voltage coil option
Teledyne has added a 3V DC coil to its 172 series of electromechanical relays to meet customer demand for the additional operating voltage
Attenuator relay runs up to 5GHz
The A152 ultraminiature broadband attenuator relay is designed for use in 50 and 75ohm systems in the DC to 5.0GHz frequency range
Features include a wide selection of attenuation ranges and step sizes, like 0 to 55dB in 1dB steps, 0 to 103dB in 1dB steps and 0 to 55.75dB in 0.25dB steps.
This attenuator has a high quality construction and connectors.
It includes a built-in TTL/CMOS interface driver circuitry.
Also special configurations are available on request.
Standard specifications are a nominal impedance of 50ohm and a frequency range from DC to 6.0GHz.
The maximum SWR shows 1.30 at DC to 3GHz and 1.45 at 3 to 6GHz.
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 feedthrough filters at each control terminal.
Devices are available from MRC Components.
