RF INPUT POWER (dBm)
Serial-Data Input/Output. Requires a pullup resistor to V
Serial-Clock Input. Requires a pullup resistor to V
No Connection. Connect this pin to ground.
RF Input. Internally matched to 75Ω. Requires a DC-blocking capacitor.
Address-Select Input. Selects the I
RF Power-Supply Input. Connect to a low-noise, power-supply voltage. Bypass to the PCB ground
plane with a 2200pF and 100nF capacitor placed as close as possible to the pin.
External Inductor Connection. Connect to V
RF Gain-Control Voltage Input. Accepts voltages from 0.4V to 2.3V with 2.3V providing maximum RF
gain. This pin can also be controlled by the OVLD_DET output. See the Typical Application Circuit.
Shutdown Input. Drive this pin low to disable all internal circuits and to put the device into low-power
shutdown mode. Drive this pin high for normal operation.
Standby Input. Controls the power-up sequence of the chip. See the Power-Up Sequence section for
more information on this pin’s operation.
Overload-Detection Output. This output provides an error signal between the internal power-detector
output voltage and an internal programmable reference voltage. This output can be connected to the
RF_AGC input to implement a closed RF automatic gain-control loop.
Baseband Power-Supply Input. Connect to a low-noise power-supply voltage. Bypass to the PCB
ground plane with a 1000pF and 100nF capacitor placed as close as possible to the pin.
