Design of a Wide-Band Front-End for a High Speed Data Acquisition System

In modern communication technology and circuit design, Data Acquisition System DAQ became the vital part of most communication. This paper introduces a wide-band front-end circuit design consists of LNA and LPF, cheap, small, reliable and widely used in various applications such as Radar, UAV, and Telemetry systems, etc. This design is mainly introduced for a wide-band high speed Data Acquisition System DAQ. In RF Circuits, front-end circuit is considered the first and the main important part of the PCB design of the DAQ card. The PCB is designed for BW (10 KHz to 400 MHz) to be implemented in the DAQ card to help filtering and amplify the signal up to 41 dB with low NF, so that the signal can meet the requirements of the digital processing.
