part itself, adding its own high frequency properties to the
overall performance of the circuit. It is good practice to have
at least one ground plane on a PCB giving a low impedance
path for all decoupling and other ground connections. In
order to achieve high immunity for unwanted signals from
outside, it is important to place the components as flat as
possible on the PCB. Be aware that a long lead can act as
an inductor, a capacitor or an antenna. A pair of leads can
even form a transformer. Careful design of the PCB avoids
oscillations or other unwanted behavior. Another important
issue is the value of components, which also determines the
sensitivity to pick-up unwanted signals. Choose the value of
resistors as low as possible, but avoid using values that
causes a significant increase in power consumption, while
loading inputs or outputs to heavily.
NSC suggests the following evaluation board as a guide for
high frequency layout and as an aid in device testing and
characterization.
