Product specication
N-channel dual-gate PoLo MOS-FETs
BF1202; BF1202R;
BF1202WR
FEATURES
Short channel transistor with high
forward transfer admittance to input
capacitance ratio
Low noise gain controlled amplifier
Partly internal self-biasing circuit to
ensure good cross-modulation
performance during AGC and good
DC stabilization.
APPLICATIONS
VHF and UHF applications with
3 to 9 V supply voltage, such as
digital and analogue television
tuners and professional
communications equipment.
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 BF1202,
BF1202R and BF1202WR are
encapsulated in the SOT143B,
SOT143R and SOT343R plastic
packages respectively.
