Vaunix Digital Attenuators
LDA Series - Portable and Programmable RF and Microwave Digital Step Attenuators
LDA Series - 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 40 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 to be 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 5G wireless systems and next-gen WIFI 6 products.
