APPLICATIONS INFORMATION

TYPICAL APPLICATION CIRCUIT

Figure 77 shows the typical application circuit for the

HMC773ALC3B. The HMC773ALC3B is a passive device and

does not require any external components. The LO and RF pins

are internally ac-coupled. When IF operation is not required

until dc, it is recommended to use an ac-coupled capacitor at

the IF port. When IF operation to dc is required, do not exceed

the IF source and sink current rating specified in the Absolute

Maximum Ratings section.

EVALUATION PCB INFORMATION

RF circuit design techniques must be implemented for the eval-

uation board PCB shown in Figure 78. Signal lines must have

50 Ω impedance, and the package ground leads and exposed

pad must be connected directly to the ground plane, similar to

that shown in Figure 78. Use a sufficient number of via holes to

connect the top and bottom ground planes. The evaluation

circuit board shown in Figure 78 is available from Analog

Devices, Inc., upon request.
