AC ELECTRICAL CHARACTERISTICS (continued)
( Typical Operating Circuit, 50Ω system impedance, AVDD = DVDD = PAVDD = +2.1V to +3.6V, f RF = 315MHz or 390MHz, T A =
-40°C to +125°C, unless otherwise noted. Typical values are at AVDD = DVDD = PAVDD = +2.7V, T A = +25°C, unless otherwise
noted. All min and max values are 100% tested at T A = +125°C, and guaranteed by design and characterization over temperature,
unless otherwise noted.)

Note 1: Supply current and output power are greatly dependent on board layout and PAOUT match.
Note 2: 50% duty cycle at 10kHz ASK data (Manchester coded).
Note 3: Guaranteed by design and characterization, not production tested.
Note 4: Dependent on PCB trace capacitance.
