Note 1: Supply current, output power, and efficiency are greatly dependent on board layout and PAOUT match.
Note 2: 100% tested at T
A
= +125°C. Guaranteed by design and characterization overtemperature.
Note 3: 50% duty cycle at 10kHz ASK data (Manchester coded).
Note 4: Guaranteed by design and characterization. Not production tested.
Note 5: Time for final signal detection; does not include baseband filter settling.
Note 6: Efficiency = P

).
Note 7: Dependent on PCB trace capacitance.
Note 8: Input impedance is measured at the LNAIN pin. Note that the impedance at 315MHz includes the 12nH inductive degenera-
tion 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 50Ω in series with ~2.2pF. The voltage conversion is measured
with the LNA input-matching inductor, the degeneration inductor, and the LNA/mixer tank in place, and does not include the
IF filter insertion loss.
