UTC A6058G-G09-T Fm front-end Datasheet

UNISONIC TECHNOLOGIES CO., LTD
A6058
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)
