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.
