Product specication
N-channel dual-gate MOS-FET
BF904WR
FEATURES
Specially designed for use at 5 V supply voltage
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 SOT343R 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.
CAUTION
The device is supplied in an antistatic package. The
gate-source input must be protected against static
discharge during transport or handling.
