The RF input and output +are designed with a 50Ω impedance, enabling direct connection between the +circuit and standard 50Ω systems. + +A micro-USB connector is used for the input power, allowing the evaluation board +to use most 5V wall wart power supplies available in the market. + +.. figure:: cn0523_simplified_block_diagram.png + + EVAL-CN0523-EBZ Block Diagram + +Reference Design Hardware +------------------------- + +Primary Side +~~~~~~~~~~~~ + +.. figure:: top_temp.jpg + + CN0523 Primary Side + +SMA Connectors +^^^^^^^^^^^^^^ + +The SMA connectors are used for the RF input and output connections: + + - **J1** is the **RF Input** SMA male connector that would be connected to a + radio or piece of RF equipment.
