EVALUATION BOARD INFORMATION
The EV1HMC520ALC4 evaluation PCB used in the application
must use RF circuit design techniques. Signal lines must have
50 Ω impedance and connect the package ground leads and
exposed pad directly to the ground plane similarly to that shown
in Figure 84. Use a sufficient number of via holes to connect the
top and bottom ground planes. The evaluation circuit board shown
in Figure 84 is available from Analog Devices, Inc., upon request
13605-085
