Description
This is Low-noise Ultra Linear UHF-VHF Amplifier.
The BF479 is a PNP silicon planar epitaxial transistor in a T-plastic package mainly intended for high current UHF-VHF stages of TV tuners. In this application, combined with a PIN diode attenulator circuit, it presents very low noise and very good cross modulation performance up to 900 MHz.
