AC ELECTRICAL CHARACTERISTICS (continued)
(
Typical Application Circuit, 50
system impedance, tuned for 315MHz to 433.92MHz operation, VAVDD = VDVDD = VPAVDD = +2.1V
to +3.6V, fRF = 300MHz to 450MHz, fCRYSTAL = 16MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VAVDD
= VDVDD = VPAVDD = +2.7V, TA = +25°C, unless otherwise noted. All min and max values are 100% tested at TA = +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.
