APPLICATIONS INFORMATION

Generate the evaluation PCB used in the application shown in

Figure 17 with proper RF circuit design techniques. Signal lines

at the RF port must have a 50 Ω impedance, and the package

ground leads and backside ground slug must connect directly to

the ground plane, as shown in Figure 18. The evaluation board

shown in Figure 18 is available from Analog Devices, Inc. upon

request.
