Use controlled impedance lines (microstrip, co-planar
waveguide, etc.) each time for high-frequency signals.
Always place decoupling capacitors as close to the
V
essary to add additional decoupling capacitors located
further from the device. Always provide a low-induc-
tance path to ground, and keep GND vias as close to
the device as possible. Thermal reliefs on GND pads
are not recommended.
