Design of a 10 GHz Low Noise Amplifier (Hebrew)

Innovation in designing state-of-the-art low-noise amplifiers in the X-band frequency range is not an easy task. The author used NI AWR Design Environment to help him design a new LNA that reached acceptable performance. This article describes how he addressed in his design five critical details: choice of the FET device, choice of the substrate and finishing, waveguide transition geometry, pass-band filter and output transition, and enclosure design to damp down oscillation problems.
