that this connection be implemented as a 50 ohm stripline. Referring to Figure 3, the width of this stripline de-
pends on the thickness of the circuit board between the stripline and the groundplane. For FR-4 type circuit board
materials (dielectric constant of 4.7), the width of the stripline is equal to 1.75 times the thickness of the circuit
board. Note that other circuit board traces should be spaced away from the stripline to prevent signal coupling, as
shown in Figure 4. The stripline trace should be kept short to minimize its insertion loss.
