NTE1843  
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: VCC = 1.6V to 6.0V  
D Excellent Supply Voltage Dependence of Loacl Oscillator: Oscillator Stop VCC = 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: (TA = +25°C unless otherwise specified)
