EVALUATION PCB INFORMATION

Use RF circuit design techniques for the circuit board used in

the application. Ensure that signal lines have 50 Ω impedance

and connect the package ground leads and the exposed pad

directly to the ground plane (see Figure 87). Use a sufficient

number of via holes to connect the top and bottom ground

planes. The evaluation circuit board shown in Figure 87 is

available from Analog Devices, Inc., upon request.
