The AD-USB4AR2 from Adaura Technologies is a 4 Channel, digital programmable attenuator that operates from 0.5 to 6 GHz. The attenuator has a attenuation range from 0 to 63 dB with a step size of 0.5 dB. It provides more than 100 dB of chain to chain isolation therby suppressing adjacent leakage levels to below receive sensitivity.
The four 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 with SMA female ports and is ideal for cellular, microwave radio, and WiFi MIMO engineering development and manufacturing test.
