Figure 4-4 Layout of the Evaluation Board
Note 1: The LNA and PA matching network was designed for minimum required space and
maximum performance and thus via holes were deliberately placed into solder pads.
In case of reproduction please bear in mind that this may not be suitable for all automatic soldering
processes.
Note 2: Please keep in mind not to layout the CLKDIV line directly in the neighborhood of the crystal
and the associated components.
Note 3: The opto part (X4) should be supplied by connecting to X3.
