UTC TA7358P LINEAR INTEGRATED CIRCUIT FM FRONT-END DESCRIPTION The UTC TA7358P 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 SIP-9 balanced type mixer circuit *Low spurious radiation *Wide operating voltage range( 1.6V to 6V) BLOCK DIAGRAM Vcc To IF AMP. 3 Input 4 6 9 Buffer AMP.
