FEATURES
APPLICATIONS
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 BF1101,
BF1101R and BF1101WR are
encapsulated in the SOT143B,
SOT143R and SOT343R plastic
packages respectively.

capacitance ratio
Low noise gain controlled amplifier
up to 1 GHz
Partly internal self-biasing circuit to
ensure good cross-modulation
performance during AGC and good
DC stabilization.
VHF and UHF applications with
3 to 7 V supply voltage, such as
television tuners and professional
communications equipment.
