Datasheet
UTC TA7358P
FM FRONT-END
DESCRIPTION
application, which is suitable to a portable radio or a radio
cassette. Comparing with conventional
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 to 6V)
