Vaunix Technology Corporation has announced the addition of three models to their family of LDA series digital attenuators. This product family now offers attenuators with up to 90 dB of programmable attenuation through 6 GHz.

The LDA-302P-H, LDA-302P-1 and LDA-302P-2 all have input power of up to 2 W and frequency coverage of 10 to 3000 MHz. All units are powered and controlled by connection to a PC or self-powered USB hub, and are programmable for fixed attenuation or swept attenuation ramps directly from the included graphical user interface (GUI) software.

Easily programmable for ATE applications, the LDA digital attenuators can also be used in WiMAX, 3G, 4G, LTE, DVB fading simulators, and engineering and production test labs.
