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: Difference in supply voltage especially between pin 1 and pin 15 is recommended to be
lower than 30mV, therefore a serial resistor in the VDD supply line, as mentioned on page 13 and
in Section 4.4, is strongly recommended.
The opto part (X4) should be supplied by connecting to X3.
