A circuit board layout using the principles illustrated in the figure above is recommended to optimize performance of
the ACMD-6103.
You must maximize isolation between the Tx and Rx ports.
High isolation is achieved by: (1) maintaining a continuous ground plane around the I/O connections and duplexer
mounting area, and (2) surrounding the I/O ports with sufficient ground vias to enclose the connections in a 'Faraday
cage.'
The ground vias under the duplexer mounting area are also needed to provide adequate heat sinking for the device.
The 2nd metal layer under the duplexer is a continuous ground plane.
