vides local decoupling at each V
one via per bypass capacitor for a low-inductance
ground connection. Also, connect the exposed paddle
to PC board GND with multiple vias to provide the low-
est inductance possible.
The layout of a matching network can be very sensitive
to parasitic circuit elements. To minimize parasitic
inductance, keep all traces short and place compo-
nents as close to the IC as possible. To minimize para-
sitic capacitance, a cutout in the ground plane (and

On the high-impedance ports (e.g., IF inputs and out-
puts), keep traces short to minimize shunt capacitance.
Keep the traces coming out of the tank short to reduce
series inductance and shunt capacitance. Keep the
inductor pads and coupling capacitor pads small to
minimize stray shunt capacitance.
