APPLICATIONS INFORMATION

TYPICAL APPLICATION CIRCUIT

Figure 40 shows the typical application circuit for the

HMC260ALC3B. The HMC260ALC3B is a passive device and

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

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

When IF operation to dc is not required, use of an external series

capacitor of a value chosen to pass the necessary IF frequency

range is recommended. 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. Ensure

that signal lines have 50 Ω impedance. Connect the package

ground leads and the exposed pad directly to the ground plane

(see Figure 41). Use a sufficient number of via holes to connect

the top and bottom ground planes. The evaluation circuit board

shown in Figure 41 is available from Analog Devices, Inc., upon

request.
