Function Description
Interface Schematic
Supply Voltage pin. External bypassing is required. The trace length
VCC
between the pin and bypass capacitors should be minimized. The
ground side of the bypass capacitor should be connected immediately
to ground plane.
Not connected.

Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.
LO input pin. This pin is internally DC-biased and should be
DC-blocked if connected to a device with a DC level present. The input
impedance is 50Ω.

LO IN
Ground connection. For best performance, keep traces physically short
and connect immediately to ground plane.

GND
RF output pin. This pin is internally DC-biased and should be
DC-blocked if connected to a device with a DC level present. This pin
must be externally matched for 50Ω output impedance.
RF OUT
Supply Voltage pin. External bypassing is required. Either a length of
transmission line or external inductor is needed between this pin and
the bypass capacitor for tuning the output to 50Ω.
