NXP Semiconductors
FEATURES
 Short channel transistor with high
 Low noise gain controlled amplifier
 Internal self-biasing circuit to
APPLICATIONS
 VHF and UHF applications with 9 V
DESCRIPTION
Enhancement type N-channel
field-effect transistor with source and
substrate interconnected. Integrated
diodes between gates and source
protect against excessive input
voltage surges. The BF1109,
BF1109R and BF1109WR are
encapsulated in the SOT143B,
SOT143R and SOT343R plastic
packages respectively.
