315MHz/433MHz ASK Superheterodyne Receiver with AGC Lock

Maxim Integrated 

315MHz/433MHz ASK Superheterodyne

Receiver with AGC Lock

AC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit, VAVDD = VDVDD = VDD5 = +3.0V to +3.6V, all RF inputs are referenced to 50Ω, fRF = 315MHz,

TA = -40°C to +105°C, unless otherwise noted. Typical values are at VAVDD = VDVDD = VDD5 = +3.3V and TA = +25°C.) (Note 1)
