NXP Semiconductors
Product specification
N-channel dual-gate MOS-FETs
BF1211; BF1211R;
BF1211WR
FEATURES
Short channel transistor with high forward transfer
admittance to input capacitance ratio
Low noise gain controlled amplifier
Excellent low frequency noise performance
Partly internal self-biasing circuit to ensure good
cross-modulation performance during AGC and good
DC stabilization.
APPLICATIONS
Gain controlled low noise VHF and UHF amplifiers for
5 V digital and analog television tuner 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 BF1211, BF1211R and BF1211WR
are encapsulated in the SOT143B, SOT143R and
SOT343R plastic packages respectively.
