FUNCTION
Power Supply. Bypass to GND with 0.01 F F capacitors as close as possible to the pin.
Single-Ended 50 I RF Input. Internally matched and DC shorted to GND through a balun. Provide a
DC-blocking capacitor if required. Capacitor also provides some RF match tuning.
Ground. Internally connected to the exposed pad. Connect all ground pins and the exposed pad
(EP) together.
LO Amplifier Bias Control. Output bias resistor for the LO buffer. Connect a 698 I Q 1% resistor
(nominal bias condition) from LOBIAS to ground. The maximum current seen by this resistor is 3mA.
Ground. Not internally connected. Ground these pins or leave unconnected.
Local Oscillator Input. This input is internally matched to 50 I . Requires an input DC-blocking
capacitor. Capacitor also provides some LO match tuning.
Ground. Connect all ground pins and the exposed pad (EP) together.
Mixer Differential IF Output/Input
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 via grounds are also required to achieve the noted RF performance (see the Layout
Considerations section).
