Description

1 to 3, 5 to 12, 14 to

16, 18

GND

Ground. These GND pins must be connected to RF and dc ground. See Figure 3 for the interface schematic.

4

LO

LO Port. The LO pin is AC-coupled and matched to 50 Ω. See Figure 4 for the interface schematic.

13

RF

RF Port. The RF pin is AC-coupled and matched to 50 Ω. See Figure 5 for the interface schematic.

17

IF

IF Port. The IF pin is DC-coupled and matched to 50 Ω. For applications not requiring operation to DC, DC block this port externally

using a series capacitor of a value chosen to pass the necessary RF frequency range. For operation to DC, the IF pin must not

source or sink more than 19 mA of current. Otherwise, device malfunction or device failure may result. See Figure 6 for the interface

schematic.

EPAD

Exposed Pad. The exposed pad must be connected to RF and dc ground.
