Low-Cost, 315MHz and 433.92MHz
ASK Transceiver with Fractional-N PLL
AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, 50 Ω system impedance, V PAVDD = V AVDD = V DVDD = V HVIN = +2.1V to +3.6V, f RF = 315MHz or
433.92MHz, T A = -40°C to +125°C, unless otherwise noted. Typical values are at V PAVDD = V AVDD = V DVDD = V HVIN = +2.7V,
T A = +25°C, unless otherwise noted.) (Note 1)

Supply current, output power, and efficiency are greatly dependent on board layout and PAOUT match.
100% tested at T A = +125°C. Guaranteed by design and characterization overtemperature.
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 OUT /(V DD x I DD ).
Dependent on PCB trace capacitance.
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 50 Ω 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.
Typical Operating Characteristics
(Typical Application Circuit, V PAVDD = V AVDD = V DVDD = V HVIN = +3.0V, f RF = 433.92MHz, IF BW = 280kHz, 4kbps Manchester encod-
ed, 0.2% BER, T A = +25°C, unless otherwise noted.)
