Vaunix LDA Attenuator Series Product Description

Portable and Programmable RF and Microwave Digital Step Attenuators

Vaunix Lab Brick LDA series RF/microwave portable and programmable digital attenuators include several 50 Ohm and 75 Ohm bi-directional step attenuators with calibrated operation in bands up to 20 GHz. These low cost, portable, USB powered, hand-held wireless test devices are ideal for engineering and production test laboratories, wireless network testing, and integration into high speed automated test equipment (ATE) benches, racks, stands, and systems. They’ve been proven the best attenuation instruments for the rapid and efficient development of wireless fading simulators for Multiple Input Multiple Output (MIMO), and Single Input Multiple Output (SIMO) wireless communication systems, such as WiMAX, 3G, 4G, and LTE. They’re also a top solid state choice of wireless test engineers exploring and deploying next-generation 5G wireless systems.

Technology

Lab Brick LDA Series portable and programmable digital step attenuators are designed with advanced solid-state attenuator technology for excellent repeatability of attenuation values. These USB powered and controlled, hand-held wireless test devices require no additional DC supply voltage. They’re portable and are easily programmable for fixed attenuation or swept attenuation ramps directly from the included Microsoft Windows compatible GUI.

Packaging and Compliance

Dual port Lab Bricks are housed in portable yet rugged aluminium enclosures, some measuring 3.86 x 2.52 x 1.35 in. (98 x 54 x 34 mm) and weighing just 0.5 lb. (0.23 kg), and others measuring 4” x 2.5” x 0.95” (101.6 x 63.5 x 23.9 mm) and weighing 0.6 lbs (0.27 Kg). (See each model’s detail page for mechanical specifications). 4 port Lab Bricks measure 7.3” x 2.5” x 0.95” (185.4 x 63.5 x 24.1 mm) and weigh 0.9 lbs (0.41 Kg). All Lab Brick LDA Digital Attenuators are RoHS compliant.
