AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, 50 Ω system impedance, PAV
DD = AV DD = DV DD = HV IN = +2.1V to +3.6V, f RF = 315MHz, 345MHz, or
433.92MHz, T A = -40°C to +125°C, unless otherwise noted. Typical values are at PAV DD = AV DD = DV DD = HV IN = +2.7V, T A = +25°C,
unless otherwise noted.) (Note 1)
