The AD-USB2A12G315 from Adaura Technologies is a 2 Channel, programmable attenuator that operates from 0.5 to 6 GHz. The attenuator has a attenuation range from 0 to 31.5 dB with a step size of 0.5 dB. It provides more than 50 dB of chain to chain isolation thereby suppressing adjacent leakage levels to below receive sensitivity.
The two channels can be controlled independently and powered via a single USB port. An easy to use GUI provides fixed attenuations as well as flexible ramp functions. Custom automation is easily accomplished via simple serial port commands on any Windows or Linux based PC. It is available in a compact module that measures 120 x 140 x 45 mm with SMA female ports and is ideal for cellular, microwave radio, and WiFi MIMO engineering development and manufacturing test.
