soldered onto the PC board. In this case, the layout in figure 2.3 would be modified to

accommodate horizontal (90°) mounting of the transceiver. If the transceiver is bent to

the left in figure 2.3, then C1 should be moved up and to the right, above L1. L1 and C2

can shift down slightly to minimize the trace lengths for L1, C1 and C2 in this

variation on the original layout. Note that the ground plane on the solder side of the

board becomes more important in this variation since the ground pin of C1 is now on the

right-hand side of the transceiver, and a low-impedance path between the ground pins

for C1 and C2 is needed.
