Integrated Circuit

FM Front End

Description:

The NTE1843 is an integrated circuit in a 9–Lead SIP type package designed for use in FM front–end

applications. Typical applications include portable radio and radio cassettes.

Compared with conventional types, supply voltage dependence, overload characteristics and spuri-

ous radiation characteristics are improved.

Features:

D Wide Supply Voltage Range: V_CC= 1.6V to 6.0V

D Excellent Supply Voltage Dependence of Loacl Oscillator: Oscillator Stop V_CC= 0.9V Typ

D Improved Inter–Modulation Charactristics by Double Balanced Type Mixer Circuit

D Low Spurious Radiation

D Built–In Clamping Diode for the Local Oscillator Output

Absolute Maximum Ratings: (T_A= +25°C unless otherwise specified)
