EVALUATION BOARD INFORMATION
The circuit board used in an application must use RF circuit
design techniques. Signal lines must have 50 Ω impedance, and
the package ground leads and exposed pad must be connected
directly to the ground plane, similarly to that shown in Figure 35.
Use a sufficient number of via holes to connect the top and
bottom ground planes. The evaluation circuit board shown in
Figure 35 is available from Analog Devices, Inc., upon request.
