TA7358P

UTC TA7358P FM FRONT-END DESCRIPTION LINEAR INTEGRATED CIRCUIT The UTC TA7358P is designed for a FM front-end application, which is suitable to a portable radio or a radio types, supply cassette. Comparing with conventional radiation characteristics are improved. voltage dependence, overload characteristics and spurious 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 to 6V) SIP-9 BLOCK DIAGRAM Vcc To IF AMP. 3 4 6 9 Local Oscillator Input B.P.F Buffer AMP. 8 7 1 RF AMP.
