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
