The LDA-302P-2 is a USB Controlled Digital Step Attenuator that operates from 10 MHz to 3 GHz with a 90 dB Attenuation range. It can handle up to 2 W of power and has an insertion loss of 4.5 dB with a 1.3:1 VSWR. The Attenuator is ideal for engineering and production test laboratories as well as integration into high speed automatic-test-equipment (ATE) systems. It 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. The module has SMA connectors can be controlled by a simple GUI on any windows based PC.
