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.
