Description
Ground – Must be connected to GND in the Application Circuit
No Internal Connection – Can be connected to GND in the Application Circuit
RF signal to/from the Transceiver (at DC this pin presents a short to GND)
PA Control (digital CMOS input)
LNA Control (digital CMOS input)
Analog output providing DC voltage proportional to PA RF Power Output
BYPASS control (digital CMOS input )
ANTENNA control (digital CMOS input; selects between A and B for diversity)
PA Output / LNA Input for Ant B (at DC this pin presents a short to GND)
PA Output / LNA Input for Ant A (at DC this pin presents a short to GND)
Inductor to GND (choice of value impacts 2^nd harmonic)
Reserved – Do Not Connect at the PCB level in the Application Circuit
Voltage Supply (Internally Connected to each other)
