GND

Ground. Connect the package bottom to RF/dc ground. See Figure 3 for the GND interface schematic.

2

LO

Local Oscillator. This pin is dc-coupled and matched to 50 Ω. See Figure 4 for the LO interface schematic.

5

IF

Intermediate Frequency. This pin is dc-coupled. For applications not requiring operation to dc, externally

block this pin using a series capacitor whose value is chosen to pass the necessary IF frequency range. For

operation to dc, this pin must not source or sink more than 12 mA of current or device nonfunction and

possible device failure results. See for Figure 5 the IF interface schematic.

8

RF

Radio Frequency. This pin is dc-coupled and matched to 50 Ω. See Figure 6 for the RF interface schematic.

10 to 12

NIC

Not Internally Connected.

EPAD

Exposed Pad. Exposed pad must be connected to RF/dc ground.
