APPLICATIONS INFORMATION

TYPICAL APPLICATION CIRCUIT

Figure 84 shows the typical application circuit for the

HMC554ALC3B. The HMC554ALC3B is a passive device

and does not require any external components. The IF pin

is internally dc-coupled. The RF and LO pins are internally

ac-coupled. When IF operation to dc is not required, using an

external series capacitor is recommended, of a value chosen to

pass 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 84). Use a sufficient

number of via holes to connect the top and bottom ground

planes. The evaluation circuit board shown in Figure 85 is

available from Analog Devices, Inc., upon request.
