AC ELECTRICAL CHARACTERISTICS

(Typical Application Circuit, 50

Ω system impedance, PAVDD = AVDD = DVDD = HVIN = +2.1V to +3.6V, fRF = 315MHz, 345MHz, or

433.92MHz, TA = -40°C to +125°C, unless otherwise noted. Typical values are at PAVDD = AVDD = DVDD = HVIN = +2.7V, TA = +25°C,

unless otherwise noted.) (Note 1)
