Digital attenuators

19 November 2014 Telecoms, Datacoms, Wireless, IoT

At the heart of Aeroflex/Weinschel’s 4205 Series is a series of USB/TTL controlled MMIC digital attenuators and Ethernet controlled, rack-mountable subsystems that is suitable for a multitude of RF and microwave applications up to 6 GHz.

Designed with budget and performance concerns in mind, these devices offer RF characteristics and performance suitable for automated bench testing in wireless backhaul, fading simulation and other high-performance wireless applications. All of these models are RoHS compliant.

The devices are available in three attenuation configurations up to 95,5 dB in 0,5 dB steps and operate over the 0,2 to 6 GHz frequency range. They are supplied with both parallel-TTL and USB 2.0 interfaces. The mode of operation is determined by the source of DC power to the unit.

The USB interface is compatible with standard USB 2.0 and is powered by the host USB connection. The attenuator operates as a USB CDC device and accepts simple ASCII text commands. This allows the unit to be controlled from any system capable of sending data via a standard COM port-style interface.

LabVIEW-based USB Control Centre Software (AUCS), which is included, can also be used in the operation of this series of digital attenuators. The AUCS will allow the user to set up, control and perform test and measurements using these digital attenuators over a standard USB 2.0 communication interface.

The low-profile design of the 4205 Series and convenient 12 mounting holes on the front, sides, top and bottom allow for mounting in any subsystem or rack configuration. With this in mind, the manufacturer also offers a standard line of half-rack (Model 8320) and full 19” rack turnkey solutions (Model 8321 and 8331) containing these devices that offer USB, Ethernet control or front panel operation. Attenuation matrices and custom configurations can also be designed using these building block components.
