Philips Semiconductors
N-channel dual gate MOS-FETs
Product specification
BF904; BF904R
FEATURES
Specially designed for use at 5 V supply voltage
Short channel transistor with high 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 SOT143B and 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.
CAUTION
This product is supplied in anti-static packing to
prevent damage caused by electrostatic discharge
during transport and handling. For further information,
refer to Philips specs.: SNW-EQ-608, SNW-FQ-302A
and SNW-FQ-302B.
