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 PC board trace capacitance.
Note 8:
The oscillator register (0x05) is set to the nearest integer result of f
XTAL
/ 100kHz (see the
Oscillator Frequency Register
sec-
tion).
Note 9:
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 approximately 50
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.
