UTC-IC TA7358P

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)
