Typical Application Circuit
Very few external components are required for the operation of
CC1200.
A typical application circuit
is shown below. Note that it does not show how the board layout should be done, which will
greatly influence the RF performance of
CC1200.
This section is meant as an introduction only. Note that decoupling capacitors for power pins are
not shown in the figure below.
