A feasibility study and the corresponding design flow for robust millimeter wave GaN LNAs is provided in this paper. Particular attention is devoted to the selection of the optimum geometry of the first stage active device. A trade-off is shown between noise performance and robustness requirements. The beneficial effects of source degenerative feedback are shown. The LNA's simulated performance are gain > 20B, NF < 1.7dB and power handling capability verified up to +20 dBm input power in CW operation. This design is well suited for operation in high reliability systems, such as space operation on airborne applications.

Abstract
A feasibility study and the corresponding design flow for robust millimeter wave GaN LNAs is provided in this paper. Particular attention is devoted to the selection of the optimum geometry of the first stage active device. A trade-off is shown between noise performance and robustness requirements. The beneficial effects of source degenerative feedback are shown. The LNA's simulated performance are gain > 20B, NF < 1.7dB and power handling capability verified up to +20 dBm input power in CW operation. This design is well suited for operation in high reliability systems, such as space operation on airborne applications.| File | Dimensione | Formato | |
