308MHz/315MHz/418MHz/433.92MHz
Low-Power, FSK Superheterodyne Receiver
AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Application Circuit, 50 ? system impedance, V AVDD = V DVDD = V HVIN = +2.4V to +3.6V, f RF = 308, 315, 418, and
433.92MHz; T A = -40°C to +125°C, unless otherwise noted. Typical values are at V AVDD = V DVDD = V HVIN = +3.0V,
f RF = 433.92MHz, P RFIN ≤ -80dBm, T A = +25°C, unless otherwise noted.)

Note 1: 0.2% BER, 4kbps, Manchester coded, 280kHz IF BW, ±50kHz frequency deviation.
Note 2: Input impedance is measured at the LNAIN pin. Note that the impedance at 315MHz includes the 3.9nH inductive degener-
ation from the LNA source to ground. The impedance at 433.92MHz includes a 0nH inductive degeneration connected from
the LNA source to ground. The equivalent input circuit is 47 ? in series with 3.2pF at 315MHz and 47 ? in series with 3.5pF
at 433.92MHz.
Note 3: 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 filter insertion loss.
Typical Operating Characteristics
(Typical Application Circuit, V DD = 3.0V, f RF = 433.92MHz, IF BW = 280kHz, data rate = 4kbps Manchester encoded, frequency
deviation = ±50kHz, BER = 0.2%, T A = +25°C, unless otherwise noted.)
