Note : Your Quotation Request will be directed to Vaunix.

The LDA-102E Lab Brick Digital Attenuator with SMA female connectors is a 50 Ohm RF step attenuator which operates from 0.1 MHz to 1 GHz. It has an attenuation range of 120 dB, an insertion loss of 5.5 dB and can handle up to 1 W of power. The attenuator is powered by the USB slot and does not require an additional DC supply voltage. It is easily programmable for fixed attenuation or swept attenuation ramps directly from the included GUI. Lab Brick Digital Attenuator API DLL and LabVIEW-compatible drivers are also available for custom programming applications. The LDA-102E Lab Brick Digital 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. It is based on GaAs monolithic-microwave-integrated-circuit (MMIC) attenuator technology for excellent repeatability of attenuation values.
