Maxim Integrated 

308MHz/315MHz/418MHz/433.92MHz

Low-Power, FSK Superheterodyne Receiver

DC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit, 50Ω system impedance, AVDD = DVDD = HVIN = +2.4V to +3.6V, fRF = 308, 315, 418, and 433.92MHz;

TA = -40°C to +125°C, unless otherwise noted. Typical values are at AVDD = DVDD = HVIN = +3.0V, fRF = 433.92MHz,

PRFIN ≤ -80dBm, TA = +25°C, unless otherwise noted.)
