FM / TV front end
BA4425F
The BA4425F is a monolithic IC designed for FM front end use. It consists of an RF amplifier circuit, mixer circuit, oscilla-
tion circuit, and IF buffer amplifier.
FApplications
FM radios
Radio cassette players
Home stereos
Headphone stereos
FFeatures
1) Uses double balance mixer to improve intermodula-
tion characteristics.
2) Includes a clamp diode in the mixer output.
3) Local oscillation buffer on-chip for improved re-
sponse to strong input.
4) The output impedance of the IF buffer is matched
with the ceramic filter impedance at 330Ω.
5) Mixer input coupling capacitor included on-chip.
6) Includes a feedback capacitor for the local oscillation
circuit.
7) Reception of VHF terrestrial TV channels is possible.
8) Compact SOP 8-pin package.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
