Description
No Connection. These pins can be left open or tied to ground.
Power Supply Common Pins. COM1, COM2, and COM3 must all be connected to a ground plane via a
low impedance path.
Device Output. Single-ended, 50 Ω internally biased RF/IF output; pin must be ac-coupled to the load.
Power Supply Pins. Decouple each pin with a 0.1 μF capacitor; Pin 8 and Pin 9 can share a single
capacitor, as can Pin 23 and Pin 24. All pins must be connected to the same supply (V
Temperature Sensor Output. Provides dc voltage proportional to die temperature. Slope is 4.6 mV/°C
Device Enable. Shuts device down when grounded and enables device when pulled to supply
voltage.
Differential In-Phase and Quadrature Baseband Inputs. These high impedance inputs must be
externally dc-biased to 500 mV dc and driven from a low impedance source. Nominal characterized
ac signal swing is 700 mV p-p on each pin (150 mV to 850 mV). This results in a differential drive of
1.4 V p-p with a 500 mV dc bias.
Single-Ended Two-Times Local Oscillator Input. This input is internally biased and must be
ac-coupled to the LO source.
Common for LO Input. Must be ac-coupled to ground through a low impedance path.
