Description

1, 12, 40

VCC_DRV, VCC_AMP,

VCC2_DRV

Supply Voltages for the RF Output Driver, 4.0 V. Place a 1 µF decoupling capacitor close to

each pin.

2, 3, 14

No Connection.

VCTR_RF

RF Gain Control, 0 V to 1.8 V.

5, 6, 8, 9

QN, QP, IP, IN

Differential Quadrature Baseband Inputs. These 50 Ω differential impedance inputs can be

common-mode dc biased from 0 V to 2.5 V.

7, 16

VCC_IF, VCC2_IF

Supply Voltages for the IF and Baseband Inputs, 3.3 V. Place a 1 µF decoupling capacitor close

to each pin.

EXT_CAP_N

IF Gain Control Capacitor Negative Terminal. To adjust the IF gain manually, this pin must be

driven externally when the AGC functionality is disabled, 0 V to 3.3 V. Note that VCTR_IF is the

voltage applied to the EXT_CAP_x pins.

EXT_CAP_P

IF Gain Control Capacitor Positive Terminal. Note that VCTR_IF is the voltage applied to the

EXT_CAP_x pins.

VCC_VVA

Supply Voltage for the Variable Gain Amplifier, 1.8 V. Place a 1 µF decoupling capacitor close

to this pin.

VCC_MIXER

Supply Voltage for the Mixer, 3.3 V. Place a 1 µF decoupling capacitor close to this pin.

VCC_DOUBLER

Supply Voltage for the Internal 2× Multiplier, 3.3 V. Place a 1 µF decoupling capacitor close to

this pin.

IF Input. This pin has a 50 Ω input impedance.

RBIAS

Resistor Band Gap Reference Bias. Place a precision 680 Ω resistor to ground at this pin.

VTUNE

VCO Tune Port, 0.5 V to 2.8 V. This pin is driven by the output of the loop filter.

VCC_BG

Supply Voltage for the Internal Band Gap, 3.3 V. Place a 1 µF decoupling capacitor close to this pin.

VG_VCO

VCO Gate Decoupling. Place a 10 µF decoupling capacitor at this pin.

VCC_VCO

Supply Voltage for the VCO, 3.3 V. Place a 1 µF decoupling capacitor close to this pin.

VCC_DIV

Supply Voltage for Fractional-N PLL, 3.3 V. Place a 1 µF decoupling capacitor close to this pin.
