Layout of CGB240 Bluetooth evaluation board used in

application note 2.

For a discrete matching concept, the same evaluation board (V1.2) as shown in fig-

ure 5 might be used. However, to insert the series elements (L2, L3, L4), the pcb

lines have to be cut mechanically.

The use of a discrete matching concept saves pcb space but will lead to a lower out-

put power (typ. 0.3dB lower) and higher BOM cost.
