Vaunix Announces LDA Digital Attenuators Now Available with N-Type Connectors

Haverhill, MA – Vaunix Technology Corporation, (, a manufacturer of USB controlled and powered test equipment, has announced additions to their LDA Digital Attenuators line. Five of their LDA Digital Attenuators are now available with N-Type Connectors.

The LDA series of Lab Brick® Digital Attenuators includes 50 Ohm RF step attenuators with calibrated operation up to 6 GHz. These units connect to a USB port for control and power and require no additional DC supply voltage. They are easily programmable for fixed attenuation or swept attenuation ramps directly from the included GUI. Lab Brick Digital Attenuator API DLL and LabVIEWcompatible drivers are also available for custom programming applications.

Lab Brick Digital Attenuators are ideal for engineering and production test laboratories as well as integration into high speed automatic-test-equipment (ATE) systems. They can also be used in development of low-cost fading simulators for Multiple Input Multiple Output (MIMO) and Single Input Multiple Output (SIMO) communication systems such as WiMAX, 3G and LTE. They are based on solid state attenuator technology for excellent repeatability of attenuation values.

The new models include: LDA-102N, .1-1000 MHz; LDA-602N, 6-6000 MHz; LDA-302P-HN, 10-3000 MHz, 2 watts, 0.5 dB; LDA-302P-1N, 10-3000 MHz, 2 watts, 1.0 dB; and LDA-302P-2N, 10-3000 MHz, 2 watts, 2.0 dB.
