The AD-USB4AR38G95 from ADAURA Technologies is a four-channel programmable attenuator that operates from 0.050 to 8 GHz. It has an attenuation range from 0 to 95 dB with a step size of 0.25 dB, interchain isolation of over 115 dB, and can handle an input power of up to 31 dBm. This attenuator has an insertion loss of less than 10.8 dB and has a switching speed of 520 ns. The addition of Ethernet allows EASY implementation into the most modern of test setups by allowing network control via HTTP web interface or direct Telnet while the USB port powers the device and allows for serial communication.
It is available in a compact module that measures 181.20 x 89.30 x 25.70 mm with SMA (F) connectors and suitable for Cellular (3G, 4G, & LTE), IoT, WiFi MIMO, Engineering Development and Automated Manufacturing Test, and U-NII-6 through U-NII-8 (5.925 to 7.125GHz) applications.
