Pin Description

FUNCTION

Supply Voltage Input. Bypass with a 100pF capacitor as close to the pin as possible.

Ground. Connect to ground plane with a low-inductance connection. Solder exposed paddle

evenly to the board ground plane.

RF Input Port to Mixer. Requires a matching network and a DC-blocking capacitor that may be part

of this network.

LO Frequency-Doubler Enable Input. Drive low to enable the LO doubler and run external LO at

half frequency. Drive high to disable the LO doubler and run external LO at full frequency.

Half-Frequency Local-Oscillator Input to LO Frequency Doubler, LO Filter, and Downconverter

Mixer. Requires a DC-blocking capacitor. Leave unconnected if this pin is not used.

Full-Frequency Local-Oscillator Input to Downconverter Mixer. Requires a DC-blocking capacitor.

Leave unconnected if this pin is not used.

Differential, Open-Collector IF Output Ports of Mixer. Requires a matching network and pull-up

inductors to VCC that can be part of this network.

Bias-Setting Resistor Connection. A resistor, RBIAS, placed from BIAS to GND sets the linearity and

supply current of the mixer.
