BFX89 – BFY90 WIDE BAND VHF/UHF AMPLIFIER DESCRIPTION : • • • SILICON PLANAR EPITAXIAL TRANSISTORS TO-72 METAL CASE VERY LOW NOISE APPLICATIONS : • • • TELECOMMUNICATIONS WIDE BAND UHF AMPLIFIER RADIO COMMUNICATIONS The BFX89 and BFY90 are silicon planar epitaxial NPN transistors produced using interdigitated base emitter geometry. They are particulary designed for use in wide band common-emitter linear amplifiers up to 1 GHz. They feature very high fT, low reverse capacitance, excellent cross modulation properties and very low noise performance. The BFY90 is complementary to the BFR99A. Typical applications include telecommunication and radio communication equipment.
