BF909 Transistor

FEATURES

· Specially designed for use at 5 V supply voltage
· High forward transfer admittance
· Short channel transistor with high forward transfer admittance to input capacitance ratio
· Low noise gain controlled amplifier up to 1 GHz
· Superior cross-modulation performance during AGC.

APPLICATIONS

· VHF and UHF applications with 3 to 7 V supply voltage such as television tuners and professional communications equipment.

DESCRIPTION

Enhancement type field-effect transistor in a plastic microminiature SOT143 or SOT143R package. The transistor consists of an amplifier MOS-FET with source and substrate interconnected and an internal bias circuit to ensure good cross-modulation performance during AGC.
