Figure 259. Receiver Matching Network on ADRV9001 Evaluation Board
The circuit in Figure 259 shows the layout topology for the chosen receiver matching network. Note the location and orientation of each
component (placement is critical for expected performance). Similarly, the circuit in Figure 260 shows the layout topology used for the
transmitter matching network (see the section for circuit details). The Transmitter Bias and Port Interface section provides more details
concerning the DC supply to the transmitter.
All the RF signals must have a solid ground reference under each path to maintain the desired impedance. None of the critical traces should
run over a discontinuity in the ground reference.
