Evaluation Board

The following diagrams show the schematic and PCB layout of the RF2052 evaluation board.The standard evaluation board

has been configured for wideband operation. Application notes have been produced showing how the device is matched and

on balun implementations for narrowband applications. The evaluation board is provided as part of a design kit (DK2052),

along with the necessary cables and programming software tool to enable full evaluation of the RF2052.
