APPLICATIONS INFORMATION

TYPICAL APPLICATION CIRCUIT

Figure 35 shows the typical application circuit for the

HMC292ALC3B. The HMC292ALC3B is a passive device and

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

are internally ac-coupled. The IF pin is internally dc-coupled.

Use an external series capacitor when IF operation is not required.

Choose a value that stays within the necessary IF frequency

range. 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

Use RF circuit design techniques for the circuit board used in

the application. Ensure that signal lines have 50 Ω impedance,

and connect the package ground leads and the exposed pad

directly to the ground plane (see Figure 36). Use a sufficient

number of via holes to connect the top and bottom ground

planes. The evaluation circuit board shown in Figure 36 is

available from Analog Devices, Inc., upon request.
