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.
