Function

1, 8

RF/IF

RF and IF Input/Output Ports. These nodes are internally tied together. RF and IF port separation is achieved

using external tuning networks.

2

GND2

Device Common (DC Ground) for RFIF Switching Circuitry.

3

LOIN

LO Input, AC-Coupled.

4, 5

GND1

Device Common (DC Ground) for LO Buffer Circuitry.

6

VPOS

Positive Supply Voltage for the Drain of the LO Buffer. A series RF choke is needed on the supply line to provide

proper ac-loading of the LO buffer amplifier.

7

GC

Gate Contact of Mixing Device. Typically not connected for high frequency mixing. Connecting capacitor

between GC and VPOS permits low frequency applications.
