Data Sheet
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.
