TYPICAL APPLICATION CIRCUIT

Figure 121 shows the typical application circuit for the ADMV1550.

The ADMV1550 is a passive device that does not require any exter-

nal components. The LO and RF pins are internally AC-coupled.

The IF pin is internally DC‑coupled. For applications not requiring

operation to DC, DC block this port externally using a series

capacitor 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 ratings specified in the Absolute Maximum

Ratings section.

EVALUATION PCB INFORMATION

The circuit board used in the application must use RF circuit

design techniques. Signal lines must have 50 Ω impedance, and

the package grounds leads and exposed pad must be connected

directly to the ground plane similarly to that shown in Figure 122.

Use a sufficient number of via holes to connect the top and bottom

ground planes. The evaluation circuit board shown in Figure 122 is

available from Analog Devices, Inc., upon request.
