Design and realization of a RF transceiver for marine identification system emphasis on VHF power amplifier

摘要

In this paper, we present the design and experimental characterization of an RF front-end suitable for automatic identification system (AIS) applications. The power amplifier (PA) is designed for class C operation at two output power level settings. The design procedure, including the choice of device, modeling for class C operation, stabilization and matching is outlined and discussed. The designed PA was fabricated and tested and was found to meet AIS requirements.
