APPLICATIONS INFORMATION

EVALUATION PRINTED CIRCUIT BOARD (PCB)

Generate the evaluation PCB used in this application with

proper RF circuit design techniques. Signal lines at the RF port

must have 50 Ω impedance, and the package ground leads and

exposed paddle must be connected directly to the ground plane

similar to what is shown in Figure 34. Use a sufficient number

of via holes to connect the top and bottom ground planes.

Mount the evaluation board to an appropriate heat sink. The

evaluation PCB shown is available from Analog Devices, Inc.,

upon request.
