Data Sheet
EVALUATION PRINTED CIRCUIT BOARD (PCB)
Use RF circuit design techniques to create the circuit board for
this application. Ensure that signal lines have 50 Ω impedance,
and connect the package ground leads and exposed paddle
directly to the ground plane similar to that shown in Figure 35.
HMC7229LS6
Use a sufficient number of via holes to connect the top and
bottom ground planes. The evaluation circuit board shown in
Figure 34 is available from Analog Devices, Inc., upon request.
