Pins 6–9 & 20–23: the capacitors should be
kept close to the pins.
Pin 11: the 1uF bypass capacitor should be
kept close to the pin.
Pin 12: the bypass capacitor at this node
should be reasonably close ot the pin.
The path leading between pins 4–10, and the
path between pins 18–24, should be kept as
short as possible.

Application Note
The bypass capacitors on the Vdd lines should
be located as close as possible to the 10 uH
inductors.
The traces leading to the RF input, and leading
away from the RF output, should be 75 ohms.
Care should be taken to keep other traces,
which may have clock signals on them, as far
away as is practical to prevent unwanted
coupling onto the signal line.
