Single-Ended 50Ω RF Input. Internally matched and DC shorted to GND through a balun. Requires
an input DC-blocking capacitor.
Ground. Internally connected to the exposed pad. Connect all ground pins and the exposed pad
(EP) together.
Power Supply. Bypass to GND with capacitors as close as possible to the pin (see the Typical
Application Circuit).
LO Amplifier Bias Control. Output bias resistor for the LO buffer. Connect a 61.9Ω ±1% resistor
from LOBIAS to V
Local Oscillator Input. This input is internally matched to 50Ω. Requires an input DC-blocking
capacitor.
Differential IF Output
Ground. Not internally connected. Ground these pins or leave unconnected.
Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses
multiple ground vias to provide heat transfer out of the device into the PCB ground planes. These
multiple ground vias are also required to achieve the noted RF performance.
