SUPPLY CURRENT vs. SUPPLY VOLTAGE
Supply current, output power, and efficiency are greatly dependent on board layout and PAOUT match.
100% tested at T
50% duty cycle at 10kHz ASK data (Manchester coded).
Guaranteed by design and characterization. Not production tested.
Time for final signal detection; does not include baseband filter settling.
Efficiency = P
Dependent on PC board trace capacitance.
Input impedance is measured at the LNAIN pin. Note that the impedance at 315MHz includes the 12nH
inductive degeneration from the LNA source to ground. The impedance at 434MHz includes a 10nH induc-
tive 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.
