1 _{Reference this number when ordering the complete evaluation PCB.}
2 _{The circuit board material is Rogers 4350.}
3 _{This is the bare PCB of the evaluation PCB kit (see Figure 83).}
It is recommended that the application circuit board use RF circuit
design techniques. Use signal lines with a 50 Ω impedance, and
connect the package ground leads and exposed pad directly to
the ground plane. Use a sufficient number of via holes to connect
the top and bottom ground planes. The evaluation circuit board
shown in Figure 83 is available from Analog Devices, Inc., upon
request.
