LINEAR INTEGRATED CIRCUIT  
FM FRONT-END  
„
DESCRIPTION  
The UTC A6058 is designed for a FM front-end application,  
which is suitable to a portable radio or a radio cassette.  
Comparing with conventional types, supply voltage dependence,  
overload characteristics and spurious radiation characteristics are  
improved.  
„
FEATURES  
* Excellent supply voltage dependence of local oscillator:  
oscillator stop VCC=0.9V(typ)  
* Improved inter-modulation characteristics by double balanced  
type mixer circuit  
* Low spurious radiation  
* Wide operating voltage range( 1.6V ~ 6V)  
Lead-free:  
A6058L  
Halogen-free: A6058G
