AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, V AVDD = V DVDD = V HVIN = +2.4V to +3.6V, f RF = 300MHz to 450MHz, T A = -40°C to +125°C, unless other-
wise noted. Typical values are at V AVDD = V DVDD = V HVIN = +3.0V, f RF = 434 MHz, T A = +25°C, unless otherwise noted.) (Note 1)

Production tested at T A = +85°C. Guaranteed by design and characterization over entire temperature range.
Guaranteed by design and characterization. Not production tested.
The oscillator register (0x3) is set to the nearest integer result of f XTAL / 100kHz (see the Oscillator Frequency Register section).
Input impedance is measured at the LNAIN pin. Note that the impedance at 315MHz includes the 15nH inductive degeneration
from the LNA source to ground. The impedance at 434MHz includes a 10nH inductive degeneration connected from the LNA
source to ground. The equivalent input circuit is 50 ? in series with 2.2pF. The voltage conversion gain is measured with the
LNA input matching inductor, the degeneration inductor, and the LNA/mixer resonator in place, and does not include the IF fil-
ter insertion loss.
