TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7358APG
FM Front−End
The TA7358APG 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
• Wide supply voltage range : VCC = 1.6~6.0V
• Excellent supply voltage dependence of local oscillator
: Oscillation stop
VCC = 0.9V (typ.)
• Improved inter−modulation characteristics by double
balanced type mixer circuit.
• Low spurious radiation.
• Built−in clampping diode for the local oscillator output.
